Jason Dere commented on HIVE-8094:
----------------------------------
Ah, didn't realize SHOW DATABASES/TABLES also supported LIKE. So yeah I guess
that part should be ok then.
Does getFunctionNamesByLikePattern() provide a superset of the functionality in
getFunctionNames()? If so, then maybe showFunctions should just use
getFunctionNamesByLikePattern() rather than having different behavior
with/without the LIKE keyword. LIKE appears to be just a decorative keyword in
the case of SHOW DATABASES/TABLES.
> add LIKE keyword support for SHOW FUNCTIONS

> and keep the patterns consistent to the way as SHOW DATABASES, SHOW TABLES.
> bq. SHOW FUNCTIONS LIKE 'foo*';
