Subject [jira] [Created] (HIVE-11554) Exchange partition outputs missing from post execute hooks
Date Fri, 14 Aug 2015 01:01:45 GMT
Paul Yang created HIVE-11554:
--------------------------------

             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.

See
{noformat}
ql/src/test/results/clientpositive/exchange_partition3.q.out
{noformat}

{noformat}
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.
