bq.  Review request for hive and Carl Steinbach.

bq.  Summary
bq.  -------
bq.  
bq.  The Hive server currently has the framework to process the Cli commands like 'set'. But
it returns an empty schema definition for these resultsets. The patch here is to add a getSchema()
to the CommandResponse interface. The SetProcessor is modified to build a schema object which
is returned with getSchema.
bq.  HiveServer is modified to call the getSchema for command cases as well.
bq.

bq.  This addresses bug HIVE-2398.

This makes it unusable for a ODBC or JDBC client to use this option.
