John Sichi commented on HIVE-1785:
----------------------------------
The way the new interface is defined, people writing the hooks will need to
keep implementing the old Pre/PostExec interfaces, even though we will no
longer be calling those methods. This will make it harder to remove cruft.
> change Pre/Post Query Hooks to take in 1 parameter: HookContext

> This way, it would be possible to add new parameters to the hooks without
> changing the existing hooks.
> This will be a incompatible change, and all the hooks need to change to the
> new API
