URL: https://issues.apache.org/jira/browse/HADOOP-868
Project: Hadoop
Issue Type: Bug
Components: mapred
Reporter: Devaraj Das
Assigned To: Devaraj Das
The mergeParts method should not hardcode the factor for the merge and instead
rely on the configured default. Also, there is an unnecessary open call made in
the method.
