Subject [jira] [Commented] (HBASE-8453) TestImportExport failing again due to configuration issues
Date Sat, 15 Jun 2013 22:39:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13684429#comment-13684429

Andrew Purtell commented on HBASE-8453:

MR tests complete for both Hadoop 1 and 2 - except for on EC2. I do not know definitively
why Hadoop 1's MiniMRCluster becomes unhappy on EC2 with this change. I could guess (similar
to Jon's rumination) but that wouldn't add anything. This change appears to solve MR related
test issues everywhere for Hadoop 2 without special casing YARN internal configs bound to
change at every release. The downside is a test only quirk (this is the MRMiniCluster's problem
- not a real MR issue on a real deploy) with Hadoop 1 on EC2.

I'm fine with holding off on committing this until someone can find the time to dump configs
at every step and eyeball them. Not sure when I'll have that time personally. Thought I'd
ping here again since I found another place where this fixes Hadoop 2 issues today. (And I
no longer care about Hadoop 1.)
