Akira Ajisaka commented on HADOOP-14683:
----------------------------------------
bq. It would be wise to use instanceof prior to blindly casting.
Generally yes, but if we use instanceof, we need to throw some Exception
explicitly, which is the same as casting without type check. I'll update
javadoc to add {{@throws ClassCastException}}.

> See HIVE-17133. Looks like the signature change is causing issues; according
> to [~jnp] this is a public API.
> Is it possible to add the old overload back (keeping the new one presumably)
> in a point release on 2.8? That way we can avoid creating yet another shim
> for this in Hive.
