Carl Steinbach commented on HIVE-2390:
--------------------------------------
I updated the description of this ticket to accurately reflect the change that
was made in this patch.
My impression is that this patch doesn't really change the situation in Hive
with respect to UNIONTYPEs -- this feature is still unusable. If I'm wrong
about this I would appreciate someone setting me straight.
> Add UNIONTYPE serialization support to LazyBinarySerDe
