[~chenheng] Thanks, yeah, trying to get your MR patch backported.... let me do
that now.
[~eclark] Let me ask. Something is up though still that we are exiting a JVM
without report.... a few of the tests need fixing/removing still.
> Experiment: Temporarily disable balancer and a few others to see if root of
> crashed/timedout JVMs

> URL: https://issues.apache.org/jira/browse/HBASE-14678
> Project: HBase
> Issue Type: Sub-task
> Components: test
> Reporter: stack
>
> Looking at recent builds of 1.2, I see a few of the runs finishing with kills
> and notice that a JVM exited without reporting back state. Running the
> hanging test finder, I can see at least that in one case that the balancer
> tests seem to be outstanding; looking in test output, seems to be still going
> on.... A few others are reported as hung but they look like they have just
> started running and are just killed by surefire.
> This issue is about trying to disable a few of the problematics like balancer
> tests to see if our overall stability improves. If so, I can concentrate on
> stabilizing these few tests. Else will just undo the experiment and put the
> tests back on line.
