Review request for hive, Ramkumar Vadali and Yongqiang He.
Summary
-------
I added the counters mentioned in the task to the MapRedStats class, and
modified HadoopJobExecHelper to collect them.
I got tired of writing the same code over and over again, so I modified the way
MapRedStats and HadoopJobExecHelper treat task counters. MapRedStats now has
an enum with all of the task counters we want to collect, it is a subset of the
enum in Task$Counter. Task is package private so the enum in it is
unavailable. MapRedStats now contains a map from the enum values to the values
of the counters, if they were set. HadoopJobExecHelper loops over the enum
values and tries to get a value for each counter. As long as the new getter
and setter methods are used the functionality is the same, in particular for
the getter, if a counter was set, it returns the value of the counter,
otherwise it returns -1.
This addresses bug Hve-2479.

Testing
-------
I ran some queries to verify the counters were being populated.
I also ran a few of the unit test queries to verify I hadn't broken anything.
Thanks,
