Subject [jira] Commented: (HIVE-701) lots of reserved keywords in hive
Date Tue, 28 Jul 2009 22:13:14 GMT


Ashish Thusoo commented on HIVE-701:

This came up on show table status. It so happens as you pointed out that status is being used
for column names and if we put it into a keyword now, it will break existing scripts. Any
ideas on how to address this? I think this is going to be tricky with antlr.

and some applications already use status as a column name, they should not break
