Review request for hive.


Summary
-------

In the CLI, if a user inputs an incorrect column name, we currently just print 
the bad column name in the query. Typically, the user needs to "describe" the 
table to figure out the correct column.

This patch prints out a list of valid column and partition names in the table 
when a user inputs an incorrect column name.

e.g., 
Error in semantic analysis: Invalid table alias or column reference 
'col_does_not_exist' (possible column names are: col1, col2)


This addresses bug HIVE-2256.
