Review request for hive and John Sichi.


Changes
-------

Revamped approach. We already uniquely assign filenames to each index query 
result, so instead of throwing those away, keep them in the 
indexIntermediateFile variable, and take the union of those input paths to 
generate the next set of input splits.


Summary
-------

Grab the indexed tables during optimized query generation, grab the associated 
path URIs, and keep those around in the Configuration object. When the job is 
passed to ExecDriver, this data is extracted and used in HiveIndexedInputFormat 
to decide whether to use the index file or delegate to the parent 
(HiveInputFormat) class. Not sure if this is robust. 


This addresses bug HIVE-2128.
