>                 Key: HIVE-11554
>                 URL: https://issues.apache.org/jira/browse/HIVE-11554
>             Project: Hive
>          Issue Type: Bug
>          Components: Query Processor
>    Affects Versions: 0.12.0, 0.13.0, 0.14.0, 1.0.0, 1.2.0
>            Reporter: Paul Yang
>
> 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,
these fields (ReadEntity and WriteEntity) are empty. 
> This is an important issue as the hook interface may be configured to perform critical
warehouse operations.

> POSTHOOK: query: -- This will exchange both partitions hr=1 and hr=2
> ALTER TABLE exchange_part_test1 EXCHANGE PARTITION (ds='2013-04-05') WITH TABLE exchange_part_test2
> POSTHOOK: type: null
> {noformat}
> The post hook should not say null.
