Subject [jira] Created: (MAPREDUCE-1555) Maybe some code of MapTask is wrong.
Date Wed, 03 Mar 2010 17:20:27 GMT
Maybe some code of MapTask is wrong.

                 Key: MAPREDUCE-1555
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1555
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task
            Reporter: Ruyue Ma


  public void write(DataOutput out) throws IOException {
    if (isMapOrReduce()) {
      splitMetaInfo = null;  // HERE:  why set null ??????


In above code, if the splitMetaInfo is set null, Second Serialization (will invoke write)
will throw NullPointerException.
