Yongzhi Chen commented on HIVE-13745:
-------------------------------------
[~kgyrtkirk]The major reason to use HiveConf is not calling
System.currentTimeMillis, it is to use the time value set in SessionState. The
System.currentTimeMillis is only called when the SessionState has not set time
value yet which is consistent with original behavior(without the fix). I do not
see any issue from that.
> UDF current_date、current_timestamp、unix_timestamp NPE
