Ashutosh Chauhan commented on HIVE-15979:
-----------------------------------------
* Standard has CHARACTER_LENGTH and CHAR_LENGTH as synonyms, can you please add
that as well?
* Please use GenericUDF interface instead of UDF. UDF interface is deprecated
and meant to be removed.
* Please add tests for NULL values. Should return NULL for both functions.
> Support character_length and octet_length
