Subject [jira] [Commented] (HIVE-10728) deprecate unix_timestamp(void) and make it deterministic
Date Thu, 21 May 2015 21:25:19 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14555085#comment-14555085

Ashutosh Chauhan commented on HIVE-10728:
-----------------------------------------

I will let [~alangates] comment on whats the policy for deprecating udfs. Throwing exception
as you have done I see breaks backward compatibility.

> We have a proper current_timestamp function that is not evaluated at runtime.
> Behavior of unix_timestamp(void) is both surprising, and is preventing some optimizations
on the other overload since the function becomes non-deterministic.
