Subject [jira] Commented: (HIVE-376) In strict mode do not allow join without "ON" condition
Date Fri, 24 Apr 2009 01:59:30 GMT

Zheng Shao commented on HIVE-376:
---------------------------------

Actually it's not in hive-default.xml. Please add it.

Also, I think we should put some hints about "set hive.mapred.mode=nonstrict" in the error
message for the negative case so user can fix it quickly. What do you think?

product and explosion of data. Very few people want to run with join condition. Usually it
is a mistake.
