Ravi Gummadi commented on MAPREDUCE-2095:
-----------------------------------------
Code changes look fine to me.
Some minor comments on the testcase:
(1) io.close() can be moved to finally block.
(2) Also, please delete the contents of rootTempDir in the finally block.
(3) Please add some javadoc to the testcase.
(4) Please include the data file wordcount.json.gz in the patch so that
committer need not have to remember the path where it is to be committed.
> Gridmix unable to run for compressed traces(.gz format).
