Sergio Peña commented on HIVE-14055:
------------------------------------
Hey Sergey, sorry I am still against the null value. I was thinking that if a
filter push down couldn't be done, then the method should throw an exception
with the reason of that. While I was running some tests with HIVE-14063, I did
a test you mentioned about falling-back to ORM if direct-sql fails, and ORM
also failed but with an exception returned by {{getNumPartitionsViaOrmFilter}}
due to problems with the filter. In this scenario, I could know exactly what
the problem was.
In my opinion, I think that we should throw a checked exception in case an
internal error happens, and let the caller decide what to do with it.
[~ashutoshc] [~sushanth] what do you think about this? I'd like to know other
opinions.
