[jira] [Commented] (MAPREDUCE-1554) If user name contains '_', then searching of jobs based on user name on job history web UI doesn't work

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13072600#comment-13072600 ] 

Luke Lu commented on MAPREDUCE-1554:
------------------------------------

Based on on the discussion in mapreduce-dev mailing list, MRv1 is going to be replaced by MRv2 in trunk, which doesn't have this problem. I suggest that you target the fix to the "stable" 0.20.20x branches.

> If user name contains underscore as part of it, then searching of jobs based on user name on job history web UI doesn't work. This is because in code, everywhere {code}split("_"){code} is done on history file name to get user name. And other parts of history file name also should *not* be obtained by using split("_").
