---------------------------------
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.
