This change adds get_workload() to ImpalaTestSuite and removes it
from all test suites that already returned 'functional-query'.
get_workload() is also removed from CustomClusterTestSuite which
used to return 'tpch'.
All other changes besides impala_test_suite.py and
custom_cluster_test_suite.py are just mass removals of
get_workload() functions.
The behavior is only changed in custom cluster tests that didn't
override get_workload(). By returning 'functional-query' instead
of 'tpch', exploration_strategy() will no longer return 'core' in
'exhaustive' test runs. See IMPALA-3947 on why workload affected
exploration_strategy. An example for affected test is
TestCatalogHMSFailures which was skipped both in core and exhaustive
runs before this change.
get_workload() functions that return a different workload than
'functional-query' are not changed - it is possible that some of
these also don't handle exploration_strategy() as expected, but
individually checking these tests is out of scope in this patch.

Python 3 changed some object model methods:
- __nonzero__ was removed in favor of __bool__
- func_dict / func_name were removed in favor of __dict__ / __name__
- The next() function was deprecated in favor of __next__
(Code locations should use next(iter) rather than iter.next())
- metaclasses are specified a different way
- Locations that specify __eq__ should also specify __hash__
Python 3 also moved some packages around (urllib2, Queue, httplib,
etc), and this adapts the code to use the new locations (usually
handled on Python 2 via future). This also fixes the code to
avoid referencing exception variables outside the exception block
and variables outside of a comprehension. Several of these seem
like false positives, but it is better to avoid the warning.
This fixes these pylint warnings:
bad-python3-import
eq-without-hash
metaclass-assignment
next-method-called
nonzero-method
exception-escape
comprehension-escape
Testing:
- Ran core tests
- Ran release exhaustive tests

Python 3 changes list operators such as range, map, and filter
to be lazy. Some code that expects the list operators to happen
immediately will fail. e.g.
Python 2:
range(0,5) == [0,1,2,3,4]
True
Python 3:
range(0,5) == [0,1,2,3,4]
False
The fix is to wrap locations with list(). i.e.
Python 3:
list(range(0,5)) == [0,1,2,3,4]
True
Since the base operators are now lazy, Python 3 also removes the
old lazy versions (e.g. xrange, ifilter, izip, etc). This uses
future's builtins package to convert the code to the Python 3
behavior (i.e. xrange -> future's builtins.range).
Most of the changes were done via these futurize fixes:
- libfuturize.fixes.fix_xrange_with_import
- lib2to3.fixes.fix_map
- lib2to3.fixes.fix_filter
This eliminates the pylint warnings:
- xrange-builtin
- range-builtin-not-iterating
- map-builtin-not-iterating
- zip-builtin-not-iterating
- filter-builtin-not-iterating
- reduce-builtin
- deprecated-itertools-function

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.
Testing:
- Ran core tests

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.
Testing:
- check-python-syntax.sh shows no errors related to print

Add the -d option and -f option to the following commands:
`hdfs dfs -copyFromLocal <localsrc> URI`
`hdfs dfs -put [ - | <localsrc1> .. ]. <dst>`
`hdfs dfs -cp URI [URI ...] <dest>`
The -d option "Skip[s] creation of temporary file with the suffix
._COPYING_." which improves performance of these commands on S3 since S3
does not support metadata only renames.
The -f option "Overwrites the destination if it already exists" combined
with HADOOP-13884 this improves issues seen with S3 consistency issues by
avoiding a HEAD request to check if the destination file exists or not.
Added the method 'copy_from_local' to the BaseFilesystem class.
Re-factored most usages of the aforementioned HDFS commands to use
the filesystem_client. Some usages were not appropriate / worth
refactoring, so occasionally this patch just adds the '-d' and '-f'
options explicitly. All calls to '-put' were replaced with
'copyFromLocal' because they both copy files from the local fs to a HDFS
compatible target fs.
Since WebHDFS does not have good support for copying files, this patch
removes the copy functionality from the PyWebHdfsClientWithChmod.
Re-factored the hdfs_client so that it uses a DelegatingHdfsClient
that delegates to either the HadoopFsCommandLineClient or
PyWebHdfsClientWithChmod.
Testing:
* Ran core tests on HDFS and S3

This includes some optimisations and a bulk move of tests
to exhaustive.
Move a bunch of custom cluster tests to exhaustive. I selected
these partially based on runtime (i.e. I looked most carefully
at the tests that ran for over a minute) and the likelihood
of them catching a precommit bug. Regression tests for specific
edge cases and tests for parts of the code that are very stable
were prime candidates.
Remove an unnecessary cluster restart in test_breakpad.
Merge test_scheduler_error into test_failpoints to avoid an unnecessary
cluster restart.
Speed up cluster starts by ensuring that the default statestore args are
applied even when _start_impala_cluster() is called directly. This
shaves a couple of seconds off each restart. We made the default args
use a faster update frequency - see IMPALA-7185 - but they did not
take effect in all tests.

This fixes all core e2e tests running on my local dockerised
minicluster build. I do not yet have a CI job or script running
but I wanted to get feedback on these changes sooner. The second
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.
Testing:
I ran tests locally as follows after having set up a docker network and
starting other services:
./buildall.sh -noclean -notests -ninja
ninja -j $IMPALA_BUILD_THREADS docker_images
export TEST_START_CLUSTER_ARGS="--docker_network=impala-cluster"
export FE_TEST=false

Two test_udfs.py tests (test_native_functions_race and
test_concurrent_jar_drop_use) spawn dozens of connections to
test Impala behavior under concurrency. These connections
use up frontend service threads and can cause shell tests
to timeout when trying to connect.
This moves both tests to a new TestUdfConcurrency custom
cluster test. The new custom cluster test uses a larger
fe_service_threads value to allow full concurrency. The
tests run serially and cannot impact other tests.
This also reduces the test dimensions for test_native_functions_race
so that it runs one configuration rather than eight.
