Kannan Muthukkaruppan commented on HBASE-3043:
----------------------------------------------

I love how this patch also speeds up operations like table disables, region reassignments etc. which might otherwise be stuck on compactions to finish.

> During rolling restarts, we'll occasionally get into a situation with our 100-node cluster where a RS stop takes 5-10 minutes.  The problem is that the RS is undergoing a compaction and won't stop until it is complete.  In a stop situation, it would be preferable to preempt the compaction, delete the newly-created compaction file, and try again once the cluster is restarted.
