Subject [jira] [Commented] (HBASE-14678) Experiment: Temporarily disable balancer and a few others to see if root of crashed/timedout JVMs

stack commented on HBASE-14678:
-------------------------------

Ok. Let me disable that one too as part of this experiment [~chenheng]

Also saw this just now

> 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.
