---------------------------------------------------------

Looking at recent builds, not bad but then this on ubuntu-1 doing HBASE-14407 NotServingRegion: hbase region closed forever against branch-1.2.

kalashnikov:hbase.git stack$ python ./dev-support/findHangingTests.py https://builds.apache.org/view/H-L/view/HBase/job/PreCommit-HBASE-Build/15635/consoleFull
Fetching the console output from the URL
Printing hanging tests
Hanging test : org.apache.hadoop.hbase.security.access.TestWithDisabledAuthorization
Hanging test : org.apache.hadoop.hbase.security.access.TestAccessController2
Hanging test : org.apache.hadoop.hbase.security.access.TestScanEarlyTermination
Hanging test : org.apache.hadoop.hbase.master.balancer.TestStochasticLoadBalancer
Printing Failing tests
Failing test : org.apache.hadoop.hbase.client.TestSnapshotCloneIndependence

> Patch build are now failing most of the time because we are dropping zombies. I confirm we are doing this on non-apache build boxes too.
> Left-over zombies consume resources on build boxes (OOME cannot create native threads). Having to do multiple test runs in the hope that we can get a non-zombie-making build or making (arbitrary) rulings that the zombies are 'not related' is a productivity sink. And so on...
> This is an umbrella issue for a zombie stomping session that started earlier this week. Will hang sub-issues of this one. Am running builds back-to-back on little cluster to turn out the monsters.
