[jira] [Created] (MAPREDUCE-3993) reduce fetch catch clause should catch RTEs as well

reduce fetch catch clause should catch RTEs as well
---------------------------------------------------

                 Key: MAPREDUCE-3993
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3993
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv1, mrv2
    Affects Versions: 0.23.1, 1.0.2
            Reporter: Todd Lipcon


When using a compression codec for intermediate compression, some cases of corrupt data can cause the codec to throw exceptions other than IOException (eg java.lang.InternalError). This will currently cause the whole reduce task to fail, instead of simply treating it like another case of a failed fetch.
