IMPALA-13890: Deflake test_coord_only_pool_one_quiescing_coord
test_coord_only_pool_one_quiescing_coord was flaky in UBSAN build for
not finding the pid of the quiescing coordinator. It is possible that
the quiescing coordinator was stil alive when the test method arrive
inside ImpalaCluster.graceful_shutdown_impalads() loop. This patch
attempt to deflake it by additionally call
coord_to_quiesce.wait_for_exit() at the end of test method. The test
method is renamed to test_coord_only_pool_one_coord_quiescing to share
prefix with test_coord_only_pool_one_coord_terminate.
This patch also harden test_coord_only_pool_one_coord_terminate by
applying the same change.
Testing:
Loop the following test command 10 times in UBSAN build:
impala-py.test --exploration=exhaustive \
-k test_coord_only_pool_one_coord \
custom_cluster/test_admission_controller.py
