[jira] [Commented] (IMPALA-12340) custom_cluster.test_catalogd_ha.TestCatalogdHA.test_two_catalogd_with_force_active fails in exhaustive tests
[ https://issues.apache.org/jira/browse/IMPALA-12340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17751801#comment-17751801 ]
Wenzhe Zhou commented on IMPALA-12340:
--------------------------------------
The issue could be re-produced by repeatedly running the test case for about 50 times in Jenkins or on local machine.
The issue was introduced by IMPALA-12304, for which we tried not to wake up the thread for update_catalogd RPC if there is no change for
elected active catalogd. Since we cannot hold mutex when calling SendUpdateCatalogdNotification(), it may cause the notification to
the condition variable not been processed. To fix the issue, revert the optimization added in IMPALA-12304.
