IMPALA-5746: Cancel all queries scheduled by failed coordinators
Executor registers the updating of cluster membership. When coordinators
are absence from the active cluster membership list, executer cancels
all the running fragments of the queries which are scheduled by the
inactive coordinators since the executer cannot send results back to
the inactive/failed coordinators. This makes executers quickly release
the resources allocated for those running fragments to be cancelled.
Testing:
- Added new test case TestProcessFailures::test_kill_coordinator
and ran the test case as following command:
./bin/impala-py.test tests/custom_cluster/test_process_failures.py\
::TestProcessFailures::test_kill_coordinator \
--exploration_strategy=exhaustive.
- Passed the core test.
