[jira] [Commented] (MAHOUT-1323)
ParallelALSFactorizationJobTest.completeJobToyExample is unstable
[ https://issues.apache.org/jira/browse/MAHOUT-1323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13756257#comment-13756257 ]
Suneel Marthi commented on MAHOUT-1323:
---------------------------------------
[~sslavic], these are random test failures that happen when you enable parallel tests. The same tests don't fail always deterministically on every run. We had seen this behavior in prep for 0.8 release and had disabled parallel tests execution.
When I run a build locally with parallel tests enabled the same tests does not fail always. We didn't have the time to troubleshoot this for 0.8 release but nevertheless this is one thing that needs to be ironed out before the next release.
Thinking loud here, we may have to redo all our present unit tests to work when parallel tests are enabled.
