Thanks mark. Okay, that clarifies. Iirc this kind of error only happens if mahout version is compiled for 1x. I can run a test to see if bigtop 0.7.0 has the same issue. Right now I'm going to test that the issue goes away when yum installing mahout from cdh .
That will confir it as a bug, then your idea to regression test will confirm it as a regression or not. > On Sep 20, 2014, at 10:53 AM, "Mark Grover (JIRA)" <[email protected]> wrote: > > > [ > https://issues.apache.org/jira/browse/BIGTOP-1453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14142017#comment-14142017 > ] > > Mark Grover commented on BIGTOP-1453: > ------------------------------------- > > Jay.
