[jira] [Created] (HBASE-23287) LogCleaner is not added to choreService

Baiqiang Zhao created HBASE-23287:
-------------------------------------

             Summary: LogCleaner is not added to choreService
                 Key: HBASE-23287
                 URL: https://issues.apache.org/jira/browse/HBASE-23287
             Project: HBase
          Issue Type: Bug
          Components: wal
    Affects Versions: 1.4.11, 1.6.0
            Reporter: Baiqiang Zhao


We found /hbase/oldWALs keeps growing, and we never use replication feature. Then we found OldWALsCleaner thread is always in WAITTING state :
{code:java}
Thread 176 (OldWALsCleaner-1): State: WAITING Blocked count: 0 Waited count: 1 Waiting on java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject@2ef05d36 Stack: sun.misc.Unsafe.park(Native Method) java.util.concurrent.locks.LockSupport.park(LockSupport.java:175) java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2039) java.util.concurrent.LinkedBlockingQueue.take(LinkedBlockingQueue.java:442) org.apache.hadoop.hbase.master.cleaner.LogCleaner.deleteFile(LogCleaner.java:185) org.apache.hadoop.hbase.master.cleaner.LogCleaner.access$000(LogCleaner.java:48) org.apache.hadoop.hbase.master.cleaner.LogCleaner$1.run(LogCleaner.java:161) java.lang.Thread.run(Thread.java:745)
{code}
Finally, we found that LogCleaner is not added to choreService, so LogCleaner doesn't run periodically.
