Namit Jain commented on HIVE-2925:
----------------------------------
I was thinking about it more - what I said above cannot be performed in a
custom hook.
In a pre-semantic hook, you dont have enough information --- the type of the
query, stats etc.
In a post-semantic hook, it is too late.
> Support non-MR fetching for simple queries with select/limit/filter
> operations only

> It's trivial but frequently asked by end-users. Currently, select queries
> with simple conditions or limit should run MR job which takes some time
> especially for big tables, making the people irritated.
> For that kind of simple queries, using fetch task would make them happy.
