stack commented on HBASE-8855:
------------------------------
The attached v2 patch makes these tests pass locally where they used fail.
Reading more, it is probably just safer allowing bigger permgen only rather
than enabling unloading and sweep. So, now I am back at Ted's original
workaround patch (bigger permgen).
Working theory is that these big tests w/ mapreduce, etc., all on new hadoop2
are causing us blow past default permgen size. ec2 builds, the jvm args were
passed to mvn on command line. Apache build sets MAVEN_OPTS = -3g. Perhaps
the latter makes it so children inherit the 3g too.
Let me play around some more.

> 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.
