Kevin Wilfong commented on HIVE-2453:
-------------------------------------
Ning, sorry for the confusion, my previous post here was older than the one on
the review board. I totally agree with you that we need to examine the syntax
tree rather than the execution plan for things like sort by, order by, etc. I
still stand by what I said on the review board.

> 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.
