> Project: Hive
> Issue Type: Bug

> The pre/post execute hook interface has fields that indicate which Hive
> objects were read / written to as a result of running the query. For the
> exchange partition operation, the read entity field is empty.
> This is an important issue as the hook interface may be configured to perform
> critical warehouse operations.
