             Summary: TeraSort Job Fails on S3
                 Key: MAPREDUCE-7216
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7216
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Prabhu Joseph
            Assignee: Prabhu Joseph


TeraSort Job fails on S3 with below exception. Terasort creates OutputPath and writes partition
filename but DirectoryStagingCommitter expects output path to not exist.

Creating partition filename in /tmp or some other directory fixes the issue.
