Subject [jira] [Created] (MAPREDUCE-6261) NullPointerException if MapOutputBuffer.flush invoked twice
Date Fri, 13 Feb 2015 20:40:12 GMT
Jason Lowe created MAPREDUCE-6261:
-------------------------------------

             Summary: NullPointerException if MapOutputBuffer.flush invoked twice
                 Key: MAPREDUCE-6261
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6261
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.5.0
            Reporter: Jason Lowe


MapOutputBuffer.flush will throw an NPE if it is invoked twice, since it blindly assumes kvbuffer
is not null yet sets kvbuffer to null towards the end of the method.
