[jira] Commented: (HIVE-513) UDFToString bug

Zheng Shao commented on HIVE-513:
---------------------------------

Are you working on the latest trunk? There was a recent change that might have fixed it.

We remove redundant conversion functions at compile time.
I tried "select cast('my string' as string) from mytable;" with the latest trunk and it correctly outputs "my string".
