Jingcheng Du commented on HBASE-13531:
--------------------------------------

It looks like the zookeeper (table lock) used by MobFileCompactor is not closed.
But the zookeeper used by MobFileCompactor comes from HMaster, it keeps 
connecting util the HMaster is shut down.
It's weird that the thread name is MobFileCompactor-pool10-t1-SendThread, it 
means the SendThread or ClientCnxn of Zookeeper is instantiated in 
MobFileCompactior, but it is supposed to be instantiated in HMaster.
