[~xuefuz], [~szehon] and [~jxiang] Can you help review the code? The test
failures above are not related.

> Key: HIVE-12215
> URL: https://issues.apache.org/jira/browse/HIVE-12215
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 2.0.0
> Reporter: Aihua Xu

> 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.

> PREHOOK: 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
> PREHOOK: type: ALTERTABLE_EXCHANGEPARTITION
> 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: ALTERTABLE_EXCHANGEPARTITION

> Seems it should also print output fields.
