Subject [jira] [Commented] (HIVE-8179) Fetch task conversion: Remove some dependencies on AST
Date Sat, 20 Sep 2014 00:54:33 GMT


Gunther Hagleitner commented on HIVE-8179:

had to change the query for udf6 slightly - so that it doesn't get converted to fetch task.
test parse needs to have a serialized plan to work...

> fetch task conversion is does some strange things:
> For instance: select * from (select * from x) t, wont get converted even though it's
the exact same operator plan as: select * from x.
> Or: select * from foo will get converted with minimal, but select <list all columns
of foo> from foo won't.
> We also check the AST for group by etc, but then do the same thing in the operator tree
> I'm also wondering why we ship with "moar" as default, but test with "minimal" in the
unit tests.
