Jerry He commented on HBASE-14575:
----------------------------------
As [~ndimiduk] mentioned, we've been doing a lot of checks for close
(store.areWritesEnabled()) in performCompaction()
Maybe we could a couple of more outside of performCompaction() and in between
we try to hold the region read lock?
bq. + readLock.lock(); // hold region open while we create scanners over
storefiles.
It is probably good to do this. But there seems to be no critical section to
protect here and can be relaxed as well?
> Reduce scope of compactions holding region lock

> Per [~devaraj]'s idea on parent issue, let's see if we can reduce the scope
> of critical section under which compactions hold the region read lock.
