Subject [jira] [Commented] (FLINK-11336) Flink HA didn't remove ZK metadata
Date Fri, 01 Mar 2019 12:59:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-11336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16781641#comment-16781641

Till Rohrmann commented on FLINK-11336:
---------------------------------------

Hi [~shengjk1], I think you are right that we should also delete the checkpoint directories
{{jobid/shared}} and {{jobId/taskowned}} if the job reaches a globally terminal state.

In order to not blow up the scope of this issue I would, however, suggest to create a separate
issue for the cleanup of these directories. This issue tries to address the problems of the
ZooKeeper meta data cleanup.
