Subject [jira] [Commented] (HIVE-9465) Table alias is ineffective when do loading dynamic partition
Date Thu, 29 Jan 2015 03:38:35 GMT

Xuefu Zhang commented on HIVE-9465:
-----------------------------------

Yeah. In that case, this JIRA should be an improvement rather than a bug. There is no bug
as this is by design. Also, you need to think about backward compatibility when proposing
your solution.
