---------------------------------

             Summary: Remove LogRollerExitedChecker
                 Key: HBASE-17053
                 URL: https://issues.apache.org/jira/browse/HBASE-17053
             Project: HBase
          Issue Type: Sub-task
          Components: wal
    Affects Versions: 2.0.0
            Reporter: Duo Zhang
            Assignee: Duo Zhang
             Fix For: 2.0.0


Now the LogRoll may exit before WAL exit but we will still write some close event to WAL when
shutting down RS. And for AsyncFSWAL, we will open a new wal writer when error occur. If LogRoller
has already exited then AsyncFSWAL will wait for ever and cause RS to hang.

It does not make sense to quit LogRoller ahead of WAL, this jira aims to change the shutdown
order.
