Phabricator commented on HIVE-3853:
-----------------------------------
njain has commented on the revision "HIVE-3853 [jira] UDF unix_timestamp is
deterministic if an argument is given, but it treated as non-deterministic
preventing PPD".
This calls for deterministic not being an annotation -
by any chance, do you know if the annotation can be overwritten dynamically --
otherwise duplicate function is OK
INLINE COMMENTS
ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFToUnixTimestamp.java:52
Can you share the code between this and unix_timestamp ?
I mean create a common class,and both the functions can extend that.
