this method has been deleted, and use HiveClientImpl.toHiveTable which use
shim to set location. In HiveClientImpl, the hive version maybe not same with
the default hive(1.2.1), so it use run time shim to setDataLocation. while
here deleted HiveUtils.toHiveTable just for runtime hive execution not to
interact with metastore.
