[jira] [Commented] (MAPREDUCE-6293) uberized job fails with the job
classloader enabled
[ https://issues.apache.org/jira/browse/MAPREDUCE-6293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14483691#comment-14483691 ]
Junping Du commented on MAPREDUCE-6293:
---------------------------------------
Thanks [~sjlee0] for reporting the issue and delivering a patch to fix it. I will help to review here.
I just found MAPREDUCE-6189 track the failure for TestMRTimelineEventHandling. Do we have other JIRAs to track other test failures? If not, I think we should file a separated JIRA to fix them.
