> Saw an IllegalStateException in catalogd logs of
> query_test/test_insert_behaviour.py::TestInsertBehaviour::test_insert_select_with_empty_resultset.
> It's pretty easy to reproduce the issue using an unpartitioned table:
> {code:sql}
> create table empty_tbl (i int);
> insert into empty_tbl select 1 from functional.alltypestiny limit 0;{code}
> In catalogd logs:

> This won't fail the INSERT since all exceptions thrown from
> createInsertEvents() are swallowed. But it's confusing and not firing an
> INSERT event as expected. Though the event is probably redundent, that's
> another issue. Hive also fires an empty INSERT event when the insert result
> set is empty.
