The following changes are included in this commit:
1. Modified the alltypesagg table to include an additional partition key
that has nulls.
2. Added a number of tests in hdfs.test that exercise the partition
pruning logic (see IMPALA-887).
3. Modified all the tests that are affected by the change in alltypesagg.

This is the first set of changes required to start getting our functional test
infrastructure moved from JUnit to Python. After investigating a number of
option, I decided to go with a python test executor named py.test
(http://pytest.org/). It is very flexible, open source (MIT licensed), and will
enable us to do some cool things like parallel test execution.
As part of this change, we now use our "test vectors" for query test execution.
This will be very nice because it means if load the "core" dataset you know you
will be able to run the "core" query tests (specified by --exploration_strategy
when running the tests).
You will see that now each combination of table format + query exec options is
treated like an individual test case. this will make it much easier to debug
exactly where something failed.
These new tests can be run using the script at tests/run-tests.sh
- executor takes report callback; passed in by ImpalaServer::FragmentExecState
- the PlanFragmentExecutor invokes profile reporting cb in background thread.
- RuntimeProfile is now thread-safe and has an RuntimeProfile::Update()
Also included:
- a number of bug fixes related to async cancellation of query
and propagation of errors through PlanFragmentExecutor/Coordinator/ImpalaServer.
- changing COUNTER_SCOPED_TIMER to SCOPED_TIMER
- derived counters: RuntimeProfile now lets you add counters that return a
value via a function call, which is useful for reporting something like normalized
ScanNode throughput; retrofitted to ScanNode and all subclasses
- changed coordinator to make cancellation atomic wrt recognition of an error status
for the overall query.
- Removed InProcessQueryExecutor from data-stream-test.
Added aggregate throughput counters to coordinator:
- all throughput counters are grouped in a sub-profile "AggregateThroughput"
- each scan node gets its own counter
- the value is aggregated across all registered backends which contain that node in
their plan fragments
This change updates the run-benchmark script to enable it to target one or more
workloads. Now benchmarks can be run like:
./run-benchmark --workloads=hive-benchmark,tpch
We lookup the workload in the workloads directory, then read the associated
query .test files and start executing them.
To ensure the queries are not duplicated between benchmark and query tests, I
moved all existing queries (under fe/src/test/resources/* to the workloads
directory. You do NOT need to look through all the .test files, I've just moved
them. The one new file is the 'hive-benchmark.test' which contains the hive
benchmark queries.
Also added support for generating schema for different scale factors as well as
executing against these scale factors. For example, let's say we have a dataset
with a scale factor called "SF1". We would first generate the schema using:
./generate_schema_statements --workload=<workload> --scale_factor="SF3"
This will create tables with a unique names from the other scale factors.
Run the generated .sql file to load the data. Alternatively, the data can loaded
by running a new python script:
./bin/load-data.py -w <workload1>,<workload2> -e <exploration strategy> -s [scale factor]
For example: load-data.sh -w tpch -e core -s SF3
Then run against this:
./run-benchmark --workloads=<workload> --scale_factor=SF3
This changeset also includes a few other minor tweaks to some of the test
scripts.
