Review request for hive and Carl Steinbach.
Changes
-------
Changes per review comments.
Added a JDBC test.
The CLI behaviour does look like a but. The JDBC and ODBC client are working
fine, but CLI is not printing the header. I will go ahead and log a separate
Jira for that.
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.

Testing

Tested with ODBC program to execute the set command. Ran Hive unit tests.

> The Hive server does process the CLI commands like 'set', 'set -v' sent by

> not schema for that resultset. This makes it unusable for a ODBC or JDBC
