Review comment:
> h migrate `UseStatement` to v2 command framework and change it to
`SetNamespaceCommand`, But Spark 3.1 and 3.2 still have `UseStatement`. Do our
changes here need to be forward compatible like Spark 3.3?
@iodone, IMO, for compatibility, you could check whether the Spark version
has the `UseStatement`. If no, use the `SetNamespaceCommand`.
