[jira] [Commented] (MAHOUT-1593) cluster-reuters.sh does not work
complaining java.lang.IllegalStateException
[ https://issues.apache.org/jira/browse/MAHOUT-1593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14076149#comment-14076149 ]
Suneel Marthi commented on MAHOUT-1593:
---------------------------------------
[~jaehoon13.ko] Mahout 0.9 doesn't support Hadoop 2x and hence the issues u r seeing. Nevertheless these need to be fixed in the present trunk for Hadoop 2x.
Since we r now using Git as source code control, could u create a Git Pull request as opposed to submitting a patch.
Also I am assuming that u r generating a patch against the present trunk and not from 0.9 codebase, correct?
