Kevin Wilfong reopened HIVE-2453:
---------------------------------
I have changed my mind. After further examination, I have noticed that some of
these flags would still not be able to be set accurately without reparsing the
query. For example, queries involving sort by and order by can become largely
indistinguishable in complicated queries, in particular if the sort by only
requires one reducer, from the point of the task/operator tree.

> 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.
