Review request for hcatalog, Francis Liu and David Capwell.
Changes
-------
I have addressed all the comments made by Francis and David. Please take a look
at the individual comments for the related changes.
Summary
-------
The current input storage driver for HBase does not use columns of the output
schema for projection. The output columns should be used to read only those
specific columns from HBase.
This addresses bug hcatalog-143.
