[jira] [Created] (FLINK-38336) Unexpected data copy during failover for ForSt statebackend

Zakelly Lan created FLINK-38336:
-----------------------------------

             Summary: Unexpected data copy during failover for ForSt statebackend
                 Key: FLINK-38336
                 URL: https://issues.apache.org/jira/browse/FLINK-38336
             Project: Flink
          Issue Type: Bug
    Affects Versions: 2.0.0, 2.1.0
            Reporter: Zakelly Lan
            Assignee: Han Yin


After failover, ForSt should take over all the SSTs when it works on DFS. However if the job start with NO_CLAIM mode, ForSt will do file copy, which is unexpected.
