[jira] Updated: (MAHOUT-113) CDInfosToolTest.testGatherInfos
failure in Mahout examples
[ https://issues.apache.org/jira/browse/MAHOUT-113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Deneche A. Hakim updated MAHOUT-113:
------------------------------------
Attachment: mahout113-patch.diff
I think I found the problem, it was caused by a bad random generation of the data. This patch should resolve the issue, I included a loop to repeat the test many times, and repeated it 100 times without any problem.
