[jira] [Commented] (MAPREDUCE-6836) exception thrown when accessing
the job configuration web UI
[ https://issues.apache.org/jira/browse/MAPREDUCE-6836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15948006#comment-15948006 ]
Haibo Chen commented on MAPREDUCE-6836:
---------------------------------------
Oops, this is caused by forgetting to close a div tag in MAPREDUCE-6787. Attaching a trivial patch to fix it. Verified in a pseudo-distributed cluster that the exception no longer shows up in the log.
