Review comment:
       As per HIVE column contract it should be case in-sensitive. But it is 
not handled properly in  query planning of "alter table {tablename} change". So 
I have added toLowerCase() in query planning also.

> Compaction for tables where a bucketed column has been renamed fails since 
> the list of bucketed columns in the StorageDescriptor doesn't get updated 
> when the column is renamed, therefore we can't recreate the table correctly 
> during compaction.
> Attached a unit test that fails.
> NO PRECOMMIT TESTS
