-----------------------------------------------------------
bq. this patch should remove the read lock in the HRegion.compact()
This is what the patch is doing:
{code}
1787 // block waiting for the lock for compaction
1788 lock.readLock().lock();
{code}
The above snippet was copied from browser which has plugin for patch files.
