Project: HBase
Issue Type: Bug
Components: wal

We found /hbase/oldWALs keeps growing, and we never use replication feature.
Then we found OldWALsCleaner thread is always in WAITTING state :
{code:java}

{code}
Finally, we found that LogCleaner is not added to choreService, so LogCleaner
doesn't run periodically.
