Review comment:
I'm kind of in between throwing a general `CatalogException` and throwing a
`TablePartitionedException`. We've been using specific exception for cases like
this in catalog impl, e.g. adding a partition to a non-partitioned table will
throw a `TableNotPartitionException`. CatalogException is mainly used for
runtime errors like network connection errors, and throwing it here will be a
kind of inconsistent behavior.
What do you guys think?
