stack commented on HBASE-8855:
------------------------------
Hmm... yeah. MAVEN_OPTS="-Xmx3g" makes these tests pass locally where they
fail if MAVEN_OPTS is smaller than this (which I think means they will start to
pass on ec2 -- will see). So, child jvms seem to be getting benefit of the
MAVEN_OPTs environment setting.
No harm upping the permgen then I'd say so tests pass for those who don't do
MAVEN_OPTs...
> TestTableInputFormatScan1/2 fail semi-silently with the hadoop 2 profile

> It looks like TestTableInputFormatScan1 and TestTableInputFormatScan2 never
> complete and surefire doesn't complain about it. Sure, you may see this:

> This is on my machine. On our local jenkins it's leaking and the processes
> never die. And this is only with Hadoop 2. It also looks like other tests are
> failing with PermGen space.
