[jira] [Commented] (MAPREDUCE-2441) regression: maximum limit of -1 + user-lmit math appears to be off

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13020466#comment-13020466 ] 

Allen Wittenauer commented on MAPREDUCE-2441:
---------------------------------------------

or the queue limit.

So where does the 266 come from?  The job was a terasort job with 1000 map tasks.
