Review request for hive and Carl Steinbach.


Summary
-------

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.
HiveServer is modified to call the getSchema for command cases as well.


This addresses bug HIVE-2398.
    https://issues.apache.org/jira/browse/HIVE-2398
