Duo Zhang commented on HBASE-17053:
-----------------------------------
Yes it calls logRolled.close when exiting in the run method, and also for WALPE.
Let me check the timed out tests.

> 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.
