Review request for hive and Siying Dong.


Summary
-------

I print the new stats out where we are already printing out the other map reduce stats for each job.


This addresses bug HIVE-2425.
    https://issues.apache.org/jira/browse/HIVE-2425


Diffs
-----

  trunk/ql/src/java/org/apache/hadoop/hive/ql/MapRedStats.java 1164320 
  trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/HadoopJobExecHelper.java 1164320 

Diff: https://reviews.apache.org/r/1697/diff


Testing
-------

I ran a query in local mode and verified the stats were not printed.
I ran a map only query and verified only the map time was printed.
I ran a query involving multiple jobs involving both map only and map and reduce, and verified that the appropriate stats were printed for each.

In all cases, I verified the query completed successfully.


Thanks,

Kevin
