Python 3 made the main dictionary methods lazy (items(),
keys(), values()). This means that code that uses those
methods may need to wrap the call in list() to get a
list immediately. Python 3 also removed the old iter*
lazy variants.
This changes all locations to use Python 3 dictionary
methods and wraps calls with list() appropriately.
This also changes all itemitems(), itervalues(), iterkeys()
locations to items(), values(), keys(), etc. Python 2
will not use the lazy implementation of these, so there
is a theoretical performance impact. Our python code is
mostly for tests and the performance impact is minimal.
Python 2 will be deprecated when Python 3 is functional.

This takes steps to make Python 2 behave like Python 3 as
a way to flush out issues with running on Python 3. Specifically,
it handles two main differences:
1. Python 3 requires absolute imports within packages. This
can be emulated via "from __future__ import absolute_import"
2. Python 3 changed division to "true" division that doesn't
round to an integer. This can be emulated via
"from __future__ import division"
This changes all Python files to add imports for absolute_import
and division. For completeness, this also includes print_function in the
import.
I scrutinized each old-division location and converted some locations
to use the integer division '//' operator if it needed an integer
result (e.g. for indices, counts of records, etc). Some code was also using
relative imports and needed to be adjusted to handle absolute_import.
This fixes all Pylint warnings about no-absolute-import and old-division,
and these warnings are now banned.

Python 3 now treats print as a function and requires
the parenthesis in invocation.
print "Hello World!"
is now:
print("Hello World!")
This fixes all locations to use the function
invocation. This is more complicated when the output
is being redirected to a file or when avoiding the
usual newline.
print >> sys.stderr , "Hello World!"
is now:
print("Hello World!", file=sys.stderr)
To support this properly and guarantee equivalent behavior
between python 2 and python 3, all files that use print
now add this import:
from __future__ import print_function
This also fixes random flake8 issues that intersect with
the changes.

We launch a background process checking whether tests are timeout in
run-all-tests.sh. When NUM_TEST_ITERATIONS is set to larger than 1,
run-all-tests.sh will repeat the tests. However, the timeout process is
killed at the end of each iteration, which fails the script when we want
to repeat tests. This patch moves the killing logic outside the loop.
This patch also adds a new variable, CLUSTER_TEST_FILES, to specify

This changes all existing Java code to be submodules under
a single root pom. The root pom is impala-parent/pom.xml
with minor changes to add submodules.
This avoids most of the weird CMake/maven interactions,
because there is now a single maven invocation for all
the Java code.
This moves all the Java projects other than fe into
a top level java directory. fe is left where it is
to avoid disruption (but still is compiled via the
java directory's root pom). Various pieces of code
that reference the old locations are updated.
Based on research, there are two options for dealing
with the shaded dependencies. The first is to have an
entirely separate Maven project with a separate Maven
invocation. In this case, the consumers of the shaded
jars will see the reduced set of transitive dependencies.
The second is to have the shaded dependencies as modules
with a single Maven invocation. The consumer would see
all of the original transitive dependencies and need to
exclude them all. See MSHADE-206/MNG-5899. This chooses
the second.
This only moves code around and does not focus on version
numbers or making "mvn versions:set" work.
Testing:
- Ran a core job
- Verified existing maven commands from fe/ directory still work
- Compared the *-classpath.txt files from fe and executor-deps

ASAN maintains stacks for each allocation and free of memory. Impala
sometimes allocates/frees memory from codegen'd code, so this means
that the number of distinct stacks is unbounded. ASAN is storing
these stacks in a hash table with a fixed number of buckets (one million).
As the stacks accumulate, allocations and frees get slower and slower,
because the lookup in this hashtable gets slower. This causes test
execution time to degrade over time. Since backend tests and custom cluster
tests don't have long running daemons, only the end to end tests are
affected.
This adds support for breaking end-to-end test execution into shards,
restarting Impala between each shard. This uses the preexisting shard_tests
pytest functionality introduced for the docker-based tests in IMPALA-6070.
The number of shards is configurable via the EE_TEST_SHARDS environment
variable. By default, EE_TEST_SHARDS=1 and no sharding is used.
Without sharding, an ASAN core job takes about 16-17 hours. With 6 shards,
it takes about 9 hours. It is recommended to always use sharding with ASAN.
Testing:
- Ran core job
- Ran ASAN with EE_TEST_SHARDS=6

it currently only removes one of the occurrences from the arguments

tests, because test-with-docker.py specifies --skip-stress and

part of the change will include the CI script and any follow-on
fixes required for the exhaustive tests.
The following fixes were required:
* Detect docker_network from TEST_START_CLUSTER_ARGS
* get_webserver_port() does not depend on the caller passing in
the default webserver port. It failed previously because it
relied on start-impala-cluster.py setting -webserver_port
for *all* processes.
* Add SkipIf markers for tests that don't make sense or are
non-trivial to fix for containerised Impala.
* Support loading Impala-lzo plugin from host for tests that depend on
it.
* Fix some tests that had 'localhost' hardcoded - instead it should
be $INTERNAL_LISTEN_HOST, which defaults to localhost.
* Fix bug with sorting impala daemons by backend port, which is
the same for all dockerised impalads.

Exposes a list of build flags via the impalad web UI. The build flags
can be viewed on the root page under the "Version" section. They can
be accessed via other tests through the debug version of the root page
(e.g. adding &json to the URL). The build flags are listed in a JSON
array so that they can be parsed easily. This should help run Impala
tests against a remote Impala cluster.
The build flags are read in CMakeLists.txt and then stored in
preprocessor variables.
Three build flags are exposed as part of this commit:
- Is_NDEBUG = [true, false]
- Whether NDEBUG was true or false at compile time
- CMake_Build_Type = [DEBUG, RELEASE, ADDRESS_SANITIZER, TIDY, UBSAN,
UBSAN_FULL, TSAN, CODE_COVERAGE_RELEASE, CODE_COVERAGE_DEBUG]
- The value of CMAKE_BUILD_TYPE at compile time
- Library_Link_Type = [DYNAMIC, STATIC]
- Derived from the compile time value of BUILD_SHARED_LIBS
There are a few other minor changes that are apart of this commit:
* The patch modifies environ.py so that it supports fetching build metadata
for both local and remote clusters.
* The tests under the tests/webserver directory were not being run because
'webserver' was not whitelisted in tests/run-tests.py. This patch fixes
that and addresses several test failures in run-tests.py.
* It reverts part of IMPALA-6947 so that their is no dependency from
start-impala-cluster.py to environ.py. The timeout discussed IMPALA-6947
is now set at compile time.
Testing:
Added new tests to webserver/test_web_pages.py to ensure that the build
flags are being set. Some tests are only run when run against a local
cluster because we have no way of getting the build info from a remote
cluster, whereas local clusters contain a .cmake_build_type file.

Following up to IMPALA-6857, it's useful for monitoring tools to see if
the pause monitor is getting triggered, and to see other GC metrics.
The Java side here, and the Thrift side, were easy enough.
However, the Impala metric implementation here caused us to call into
the frontend to read through the JMX memory beans 72 times, because each
call to GetValue() was getting all the data for the pool. This structure
made it hard to add additional, non-pool, metrics, and it felt wasteful.
To combat this, I added a cache of 10 seconds for getting the metrics
from the Frontend. The counters will typically re-use the same data.
There are five metrics here, and to avoid yet another enum class, I used
C++ lambdas to capture which field of the Thrift object I care about. If
folks like the approach, I think it can simplify way the enums for the
pool metrics as well.
I measured the cost of calling into the metrics code by
looping the metrics-gathering 100 times and looking at CPU
time for the process using this script:
START_CPU=$(cat /proc/$(fuser 25000/tcp 2> /dev/null | tr -d ' ')/stat | awk '{ print $14 + $15 }')
for i in $(seq 100); do
curl http://localhost:25000/jsonmetrics?json > /dev/null 2> /dev/null
done
END_CPU=$( cat /proc/$(fuser 25000/tcp 2> /dev/null | tr -d ' ')/stat | awk '{ print $14 + $15 }')
echo $START_CPU $END_CPU $(($END_CPU - $START_CPU))
On a release build on my development machine, gathering metrics 100
times took 0.16 cpu seconds without this change and 0.07 cpu seconds
with this change. The measurement accuracy here is 0.01 (I spot-checked
this with using the cpuacct cgroup infrastructure which gives you nanos,
but it was more painful to script), but this convinces me that this is a
net improvement.

Many of the test modules included calls to 'logging.basicConfig' at
global scope in their implementation. This meant that by just importing
one of these files, other tests would inherit their logging format. This
is typically a bad idea in Python -- modules should not have side
effects like this on import.
The format was additionally inconsistent. In some cases we had a "--"
prepended to the format, and in others we didn't. The "--" is very
useful since it lets developers copy-paste query-test output back into
the shell to reproduce an issue.
This patch fixes the above by centralizing the logging configuration in
a pytest hook that runs prior to all pytests. A few other non-pytest
related tools now configure logging in their "main" code which is only
triggered when the module is executed directly.
I tested that, with this change, logs still show up properly in the .xml
output files from 'run-tests.py' as well as when running tests manually
from impala-py.test

This commit tackles a few additions and improvements to
test-with-docker. In general, I'm adding workloads (e.g., exhaustive,
rat-check), tuning memory setting and parallelism, and trying to speed
things up.
Bug fixes:
* Embarassingly, I was still skipping thrift-server-test in the backend
tests. This was a mistake in handling feedback from my last review.
* I made the timeline a little bit taller to clip less.
Adding workloads:
* I added the RAT licensing check.
* I added exhaustive runs. This led me to model the suites a little
bit more in Python, with a class representing a suite with a
bunch of data about the suite. It's not perfect and still
coupled with the entrypoint.sh shell script, but it feels
workable. As part of adding exhaustive tests, I had
to re-work the timeout handling, since now different
suites meaningfully have different timeouts.
Speed ups:
* To speed up test runs, I added a mechanism to split py.test suites into
multiple shards with a py.test argument. This involved a little bit of work in
conftest.py, and exposing $RUN_CUSTOM_CLUSTER_TESTS_ARGS in run-all-tests.sh.
Furthermore, I moved a bit more logic about managing the
list of suites into Python.
* Doing the full build with "-notests" and only building
the backend tests in the relevant target that needs them. This speeds
up "docker commit" significantly by removing about 20GB from the
container. I had to indicates that expr-codegen-test depends on
expr-codegen-test-ir, which was missing.
* I sped up copying the Kudu data: previously I did
both a move and a copy; now I'm doing a move followed by a move. One
of the moves is cross-filesystem so is slow, but this does half the
amount of copying.
Memory usage:
* I tweaked the memlimit_gb settings to have a higher default. I've been
fighting empirically to have the tests run well on c4.8xlarge and
m4.10xlarge.
The more memory a minicluster and test suite run uses, the fewer parallel
suites we can run. By observing the peak processes at the tail of a run (with a
new "memory_usage" function that uses a ps/sort/awk trick) and by observing
peak container total_rss, I found that we had several JVMs that
didn't have Xmx settings set. I added Xms/Xmx settings in a few
places:
* The non-first Impalad does very little JVM work, so having
an Xmx keeps it small, even in the parallel tests.
* Datanodes do work, but they essentially were never garbage
collecting, because JVM defaults let them use up to 1/4th
the machine memory. (I observed this based on RSS at the
end of the run; nothing fancier.) Adding Xms/Xmx settings
helped.
* Similarly, I piped the settings through to HBase.
A few daemons still run without resource limitations, but they don't
seem to be a problem.

Allows running the tests that make up the "core" suite in about 2 hours.
By comparison, https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/buildTimeTrend
tends to run in about 3.5 hours.
This commit:
* Adds "echo" statements in a few places, to facilitate timing.
* Adds --skip-parallel/--skip-serial flags to run-tests.py,
and exposes them in run-all-tests.sh.
* Marks TestRuntimeFilters as a serial test. This test runs
queries that need > 1GB of memory, and, combined with
other tests running in parallel, can kill the parallel test
suite.
* Adds "test-with-docker.py", which runs a full build, data load,
and executes tests inside of Docker containers, generating
a timeline at the end. In short, one container is used
to do the build and data load, and then this container is
re-used to run various tests in parallel. All logs are
left on the host system.
Besides the obvious win of getting test results more quickly, this
commit serves as an example of how to get various bits of Impala
development working inside of Docker containers. For example, Kudu
relies on atomic rename of directories, which isn't available in most
Docker filesystems, and entrypoint.sh works around it.
In addition, the timeline generated by the build suggests where further
optimizations can be made. Most obviously, dataload eats up a precious
~30-50 minutes, on a largely idle machine.
This work is significantly CPU and memory hungry. It was developed on a
32-core, 120GB RAM Google Compute Engine machine. I've worked out
parallelism configurations such that it runs nicely on 60GB of RAM
(c4.8xlarge) and over 100GB (eg., m4.10xlarge, which has 160GB). There is
some simple logic to guess at some knobs, and there are knobs. By and
large, EC2 and GCE price machines linearly, so, if CPU usage can be kept
up, it's not wasteful to run on bigger machines.

IMPALA-6551: Change Kudu TPCDS and TPCH columns to DECIMAL

- Fix the query selection. Add additional queries that weren't matching

- Add a test that will at least ensure if
testdata/workloads/tpc*/queries is modified, the stress test will
still find the same number of queries for the given workload. There's
no obvious place to put this test: it's not testing the product at

- Move the test from IMPALA-6441 into tests/infra.
Testing:
- Core private build passed. I manually looked to make sure the moved
and new tests ran.
- Short stress test run. I checked the runtime info and saw the new
TPCDS queries in the JSON.
- While testing on hardware clusters down stream, I noticed...

TPC-DS Q67A is 10x more expensive to run without spilling than any

These stress tests were sometimes causing the end-to-end tests to hang
indefinitey, including in the pre-merge testing (sometimes called
"GVO" or "GVM").
This patch also prints to stdout some connections metrics that may
prove useful for debugging stress test hangs in the future. The
metrics are printed before and after stress tests are run when
run-tests.py is used.

In the shell, double-quoted strings are not very close to "raw"
strings; double quotes end the string, but parameter expansion is also
performed forstrings like "${FOO}". To pass strings from Python to the
shell, I have replaced double quotes with single quotes and escaped
the single quote characters in the strings.
While I am here, add better logging in TestExecutor.run_tests to make
errors like this easier to diagnose.

run-tests.py is a wrapper around impala-py.test. It abstracts away
the need to invoke separate runs for serial tests, parallel tests,
and metric verification tests.
Because it's possible for a user to specify certain test suites,
or even specific tests, on the command line when calling
run-tests.py, it had been necessary to override the command line
args when it came time to run the metric verification tests --
otherwise those other tests/suites would be rerun. Before this
patch, we had simply been stripping away all command line args.
However, that blanket approach causes problems when running tests
against a remote cluster, because we need to retain those command
line args that pertain to the remote cluster.
This patch selectively prunes unwanted command line args for the
last metric verification test stage, keeping the ones that we
need, and also adds extensive documentation for explaining why we
have to go through this fairly odd and elaborate step.
This patch was tested by running a sample test suite locally,
and against a remote cluster. Previously, the metric verification
stage had been failing for remote cluster tests (since they were
defaulting to localhost for services that were only available
remotely.) With the patch, the remote verfification tests were
passing.
Also, while I'm here, add a small change that exits immediately
if the user calls for --help. Before this, we actually still ran
the tests.

The problem: By default, all file descriptors opened by a process,
including sockets, are inherited by any forked child processes. This
includes the connection socket created at the beginning of each test
in ImpalaTestSuite.setup_class(). In
TestHiveMetaStoreFailure.test_hms_service_dies(), the Hive Metastore
is stopped and restarted, meaning the metastore in now a child process
of the test process. This causes the client connection not to be
closed when the parent process (the test) exits, meaning that one of a
finite number of connections (64) to Impala is left permanently in
use.
This would be barely noticeable except run-tests.py runs the mini
stress test with 4 * <num CPUs> concurrent clients by default. On our
build machines, this is 64 clients, which is also the default max
number of connections for an impalad. When a test process tries to
make the 65th connection (since the leaked connection is still there),
it blocks until a connection is freed up. Due to a quirk of the xdist
py.test plugin that I don't fully understand, the test framework will
not clean up test classes (and close the connections) until a number
of tests complete, causing the test process to deadlock.
The solution: use the close_fds argument to make sure the TCP socket
is closed in the spawned child process. This is also done in
CustomClusterTestSuite._start_impala_cluster() when it starts the new
cluster.
This patch also switches test_hms_failure.py to use check_call()
instead of call(), and explicitly caps the number of stress clients at
64.

This patch does a few things:
1) Move the metadata tests into their own folder under tests/. I think it's useful to
loosely categorize them so it's easier to run a subset of the tests that are most
useful for the changes you are making.
2) Reduce the test vectors for query_tests. We should have identical coverage in
the daily exhaustive runs but the normal runs should be much better. In particular,
deemphasizing scanner tests since that code is more stable now.
3) Misc test cleanup/consolidate python test files/etc.

This patch fixes a slightly pathological state that occurs when the
statestore is under heavy load. The result of the bug is that
subscribers cannot successfully re-register because the statestore never
marks them as failed.
The exact sequence of events is as follows:
1. Subscriber registers with state-store.
2. Statestore does not send heartbeats in timely fashion to
subscriber. Subscriber times-out.
3. Subscriber is restarted quickly. Statestore does not detect
restart.
4. Subscriber's RegisterSubscriber() call fails, because statestore
detects duplicate registration.
5. Subscriber restarts again. Since state-store is slow to send
heartbeats, the state-store has not detected the restart and the
subscriber receives a heartbeat message from the statestore and
does not reject it.
6. Statestore continues to believe subscriber is alive, since the
heartbeats are not being rejected.
To fix this, we add a registration ID to each successfully registered
subscriber that is known to both subscriber and statestore. If the
subscriber should restart and re-register, it receives a new
registration ID. Whenever a heartbeat arrives, it compares its
registration ID to that sent by the statestore with the heartbeat, and
rejects the heartbeat if they do not match.
We also allow re-registration of existing subscribers (getting rid of
the dreaded "Duplicate subscription" message). A new registration
overwrites an old one.

* API tests: Can all the supported API endpoints be called successfully?
* Query lifecycle tests: does calling the API in an unusual sequence
result in reasonable behaviour?
* Malformed query tests: does sending an incorrectly constructed request
correctly result in an error?
This patch adds a few simple tests as a starting point for a larger test suite.
