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

I'm abandoning this change.

In order to determine if a script is used in the mapper or reducer, I believe I 
would need to go through all the Map Reduce tasks' operators looking for 
Transform operators.  That's more work than I would like to perform for a 
feature which most users probably won't use, so I would add that to a hook.  As 
long as I have to do that work in a hook in order to get that classification, I 
can get the other categorizations with minimal additional effort.

> 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.
