Change subject: IMPALA-9262: Bump statestore_heartbeat_frequency_ms in test_kill_impalad_with_running_queries ...................................................................... IMPALA-9262: Bump statestore_heartbeat_frequency_ms in test_kill_impalad_with_running_queries CustomClusterTestSuite sets statestore_heartbeat_frequency_ms to 50, overriding the default value of 1000. This means that if a node does not respond to heartbeats for 500 milliseconds, it will time out and be removed from the cluster (vs the default of 10 seconds). A low value for statestore_heartbeat_frequency_ms is problematic for test_kill_impalad_with_running_queries because if a node is removed from the cluster membership, it is removed from the blacklist as well. The test asserts that "Blacklisted Executors" shows up in the runtime profile of a query immediately after running a query that causes a node to be blacklisted. Thus, there is a race condition between running the test query vs. the node being removed from the cluster membership. Increasing the value of statestore_heartbeat_frequency_ms should significantly reduce the chances of such a race. Testing: * Ran test_kill_impalad_with_running_queries locally * Not actually able to re-produce the flakiness locally Change-Id: I84e884efab35649b63db1a7a3b8c49b95b0b4648 --- M tests/custom_cluster/test_blacklist.py 1 file changed, 2 insertions(+), 1 deletion(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/31/15131/1 -- To view, visit http://gerrit.cloudera.org:8080/15131 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I84e884efab35649b63db1a7a3b8c49b95b0b4648 Gerrit-Change-Number: 15131 Gerrit-PatchSet: 1 Gerrit-Owner: Sahil Takiar <[email protected]>
