Subject [jira] [Commented] (HBASE-8855) TestTableInputFormatScan1/2 fail semi-silently with the hadoop 2 profile
Date Mon, 08 Jul 2013 23:59:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13702657#comment-13702657
] 

Jean-Daniel Cryans commented on HBASE-8855:
-------------------------------------------

bq. I looked in apache surefire logs and doesn't have OOMEs in the one I looked at.

Yeah I didn't see any either and the test results show TestTableInputFormatScan1/2.

bq. Weird they keep going and satisfy any test assertion (Are there any?).

They do but the thing that reports back might not be run.

> 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.
