Subject [jira] Commented: (HIVE-287) count distinct on multiple columns does not work
Date Fri, 02 Jul 2010 14:38:55 GMT

Ashish Thusoo commented on HIVE-287:
------------------------------------

@John

Another disadvantage for doing C that I can think of is the fact that count would become a
keyword and then any column names would have to be quoted. Not a big deal but just something
that would be a side effect of going with C.
