Yongzhi Chen commented on HIVE-11217:
-------------------------------------
Without the patch, for query create table t2 as select null from t1, hive
returns success with type void. I think the void type is not good for we can
not create table with type void like create table foo (aaa void). And for CTAS
with ORC format, hive throws the error.
So we have 3 choices:
1. Fix ORC, let it succeeds with type void.
2. Fix all the format scenarios, let hive return success with type string.
(This patch)
3. Throw errors for all the formats.
[~ashutoshc], I am fine with choice 2 or 3. Do you still prefer choice 3?
[~gauravkohli], how do you think?
Thanks
