Review request for hive and John Sichi.
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.

> Make automatic indexing work with jobs which access multiple tables. We'll probably need to modify the way that the index input format works in order to associate index formats/files with specific tables.
