             Summary: Add Abortable support to mapreduce tasks
                 Key: MAPREDUCE-7121
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7121
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: client
    Affects Versions: 3.0.2
            Reporter: Brandon Scheller
             Fix For: 3.2.0


This patch adds abortable to mapreduce outputs

In the case of using a remote filesystem with mapreduce, upon task attempt failure we ensure the file output stream gets aborted before being closed which prevents partial results from being uploaded.
