In PipeMarRed.java, log related fields seems useless
----------------------------------------------------
Key: HADOOP-1389
URL: https://issues.apache.org/jira/browse/HADOOP-1389
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.12.3
Reporter: Devaraj Das
Fix For: 0.13.0
In PipeMapRed.java, the fields log_ & LOGNAME seems useless since they remain
null throughout. It might cause issues at PipeMapRed.java:[line 352]. Also, the
field mapRedKey_ in the same file is always null and might cause issues if the
getContext() method is ever invoked (it is never invoked in the current code).
We possibly can remove references to these fields.
