Review request for hive, Ramkumar Vadali and Yongqiang He.


Changes
-------

I added everything from Task$Counter except CPU_MILLISECONDS because currently 
that receives special treatment in HadoopJobExecHelper.


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 Hive-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,

Kevin

> We should log more of the Hadoop task tracker counters in the MapRedStats 
> class, in order to make them available to hooks and improve logging.  
> Specifically these are the counters we should add:
>     MAP_SPILL_CPU,
>     MAP_SPILL_WALLCLOCK,
>     MAP_SPILL_NUMBER,
>     MAP_SPILL_BYTES,
>     MAP_MEM_SORT_CPU,
>     MAP_MEM_SORT_WALLCLOCK,
>     MAP_MERGE_CPU,
>     MAP_MERGE_WALLCLOCK,
>     REDUCE_SHUFFLE_BYTES,
>     REDUCE_COPY_WALLCLOCK,
>     REDUCE_COPY_CPU,
>     REDUCE_SORT_WALLCLOCK,
>     REDUCE_SORT_CPU,
>     MAP_TASK_WALLCLOCK,
>     REDUCE_TASK_WALLCLOCK,
>     MAP_INPUT_BYTES
