[jira] [Created] (MAPREDUCE-5134) Default settings cause LocalJobRunner to OOME

Sandy Ryza created MAPREDUCE-5134:
-------------------------------------

             Summary: Default settings cause LocalJobRunner to OOME
                 Key: MAPREDUCE-5134
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5134
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 2.0.3-alpha
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


If I run a job using the local job runner with vanilla settings, I get an out of memory error.  This seems to be because the default client memory maximum is 128 MB, and the default io.sort.mb is 100 MB.
