Navis commented on HIVE-4392:
-----------------------------
I've understood this issue is for temporal stopgap. Wasn't it?
Making a column as VHC does not affect resolving it in "having" or others and
just affects "select" clause. And changing aggregation columns to VHC might
make backward compatibility issue (different schema).
