Ah, my bad, when saying "just refer to `NativeCommand`", I actually meant
to add a `DescribeCommand` following `NativeCommand` in `hiveOperations.scala`.
Actually, as briefly mentioned at the end of section [PR
Overview](https://github.com/apache/spark/pull/1071#issue-35616519) of PR #1071
description, we should specialize all native commands in the same way, and use
`NativeCommand` as a default handler for those commands that haven't been
specialized yet.
