--------------------------------
Summary: Exchange partition outputs missing from post execute hooks
Key: HIVE-11554
URL: https://issues.apache.org/jira/browse/HIVE-11554
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 1.2.0, 1.0.0, 0.14.0, 0.13.0, 0.12.0
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.
