Namit Jain commented on HIVE-1546:
----------------------------------
Would it be possible to do it via a hook ?
Do you want to allow a subset of operations ? The hook is not very advanced
right now, and you cannot change the query plan etc.
But, it might be good enough for disallowing a class of statements. We can add
more parameters to the hook if need be.
That way, the change will be completely outside hive, and we will be able to
use the existing client, but with a limited functionality.
