[jira] [Updated] (MAPREDUCE-2441) regression: maximum limit of -1 doesn't appear to be unlimited anymore

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Allen Wittenauer updated MAPREDUCE-2441:
----------------------------------------

    Attachment: capsched.xml

This is our capacity scheduler configuration.  On a test grid with 762 map slots, the first user in running in the default queue only got 266 map slots.  This doesn't appear to be either the user limit or the max limit.
