> Key: KUDU-2963
> URL: https://issues.apache.org/jira/browse/KUDU-2963
> Project: Kudu
> Issue Type: Improvement
> Components: master
> Affects Versions: 1.11.0
> Reporter: Adar Dembo
> Assignee: Bankim Bhavsar
> Priority: Major
> Labels: newbie
>
> This is a problem when there aren't enough live tservers upon which to place
> a tablet's replicas, or when a chosen tserver doesn't create the replica
> quickly enough. If the catalog manager decides to replace the tablet, the
> replaced tablet's CreateTablet RPCs continue to retry ad infinitum. If the
> previously dead tservers then come back to life, they must needlessly process
> the CreateTablet RPCs.
> The tablets are eventually deleted, either through explicit DeleteTablet RPCs
> (triggered by the catalog manager replacement process), or by heartbeating,
> but it's an unnecessary drain on cluster resources.
> We should probably abort CreateTablet RPCs for tablets that have been removed
> from their table.
> CreateTableITest_TestCreateWhenMajorityOfReplicasFailCreation demonstrates
> this acutely.
