Subject [jira] [Commented] (MAPREDUCE-3185) RM Web UI does not sort the columns in some cases.
Date Fri, 14 Oct 2011 16:48:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13127686#comment-13127686
] 

Robert Joseph Evans commented on MAPREDUCE-3185:
------------------------------------------------

If there are lots of apps in the apps table it will try to fetch some of them using AJAX.
 There is probably a mismatch between the JSON returned from the call, and what the data table
needs.  Looks like we added in a column some where and forgot to update the JSON.
