Kevin Wilfong commented on HIVE-2453:
-------------------------------------

I have a test case, very similar to this query, in query_properties.q  It will get tagged,
as join and group by (not join followed by group by).

> We need a way to categorize queries, such as whether or not the include a join clause,
a group by clause, etc., in the hooks.  This will allow for better performance logging.
> Currently the only way I can find is to go through the operators in the tasks, but which
operators are used for the different types of queries may change over time.
