> Provide option for GenericUDTFGetSplits to return only schema metadata

> Project: Hive

>
>
> For some uses cases it is necessary to know the output schema for a HiveQL
> before executing the query. But there is no existing client API that provides
> this information.
> Hive JDBC doesn't provide the schema for parametric types in
> {{ResultSetMetaData}}.
> GenericUDTFGetSplits bundles the proper schema metadata with the fragments
> for input splits. An option can be added to return only the schema metadata
> from compilation, and the generation of input splits can be skipped.
