> 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
> {noformat}
> Seems it should also print output fields.
