Currently we are using "show ..." and "describe ..." to retrieve table and column information. However this is not very useful for object search. We have the following options:

1. Add catalog table support in the Hive driver so that we can use the "WHERE ..." syntax to do the object search.

2. Have a special case for Hive Object Search such that we continue to use the "show..." and "describe..." commands and do the filtering and searching in memory.
