Subject [jira] [Created] (MAPREDUCE-5236) JobConf should not support disabling memory limits
Date Thu, 09 May 2013 22:45:16 GMT
Sandy Ryza created MAPREDUCE-5236:
-------------------------------------

             Summary: JobConf should not support disabling memory limits
                 Key: MAPREDUCE-5236
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5236
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.0.4-alpha
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


In MR1, a special value of -1 could be given for mapreduce.job.map|reduce.memory.mb to disable
memory limits.  In MR2, this makes no sense, as with slots gone, this value is used for requesting
resources and scheduling.
