Jason Dere commented on HIVE-8094:
----------------------------------
Hey Thejas, yeah I think you're right about your comment about
FunctionRegistry.mFunctions and HS2. So all users would be able to see the temp
functions that have been created in HS2. I suspect you may not be able to use
them however, if the jar has not been added to the session's classloader then
the actual MR tasks may not be able to resolve UDF classes.
> add LIKE keyword support for SHOW FUNCTIONS
