Subject [jira] [Commented] (HBASE-8855) TestTableInputFormatScan1/2 fail semi-silently with the hadoop 2 profile
Date Mon, 08 Jul 2013 18:17:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13702216#comment-13702216
] 

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...

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

And this is only with Hadoop 2. It also looks like other tests are failing with PermGen space.
