Subject [jira] [Commented] (MAPREDUCE-6126) (Rumen) Rumen tool returns error "ava.lang.IllegalArgumentException: JobBuilder.process(HistoryEvent): unknown event type"

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14179537#comment-14179537

Junping Du commented on MAPREDUCE-6126:
---------------------------------------

Thanks [~jianhe] for review and comments. 
Yes. But I cannot find other event that could cause this exception. May be somewhere else
could write NormalizedResourceEvent as well? Anyway, I think the safe way to do is: handle
NormalizedResourceEvent in JobBuilder but log a warn message to say that event should be ignored
before. Also, I think we should improve the log to log the actual event that cannot be handled.

Will deliver a quick update on patch soon.
