Hao Hao reassigned KUDU-2718: ----------------------------- Assignee: Hao Hao > master_failover-itest when HMS is enabled is flaky > -------------------------------------------------- > > Key: KUDU-2718 > URL: https://issues.apache.org/jira/browse/KUDU-2718 > Project: Kudu > Issue Type: Bug > Components: test > Affects Versions: 1.9.0 > Reporter: Adar Dembo > Assignee: Hao Hao > Priority: Major > Attachments: master_failover-itest.1.txt > > > This was a failure in > HmsConfigurations/MasterFailoverTest.TestDeleteTableSync/1, where GetParam() > = 2, but it's likely possible in every multi-master test with HMS integration > enabled. > It looks like there was a leader master election at the time that the client > tried to create the table being tested. The master managed to create the > table in HMS, but then there was a failure replicating in Raft because > another master was elected leader. So the client retried the request on a > different master, but the HMS piece of CreateTable failed because the HMS > already knew about the table. > Thing is, there's code to roll back the HMS table creation if this happens, > so I don't see why the retried CreateTable failed at the HMS with "table > already exists". Perhaps this is a case where even though we succeeded in > dropping the table from HMS, it doesn't reflect that immediately? > I'm attaching the full log. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
