Andrew Purtell commented on HBASE-15697:
----------------------------------------
bq. But the better fix is that we need to ensure that compaction runs
frequently and they are getting cleared.
Can we also apply these changes to trunk? They sound like nice test
improvements. Plus, it would be weird it branch-1 gets something trunk does not.

> On my dev box TestHRegion takes about 90 seconds to complete in master and
> about 60 seconds in 0.98, but about 370 seconds in branch-1. Furthermore
> TestHRegion in branch-1 blew past my open files ulimit. I had to raise it
> from default in order for the unit to complete at all.
> I am going to bisect the recent history of branch-1 in search of a culprit
> and report back.
