Subject [jira] [Updated] (HIVE-12215) Exchange partition does not show outputs field for post/pre execute hooks
Date Mon, 19 Oct 2015 19:30:27 GMT

     [ https://issues.apache.org/jira/browse/HIVE-12215?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aihua Xu updated HIVE-12215:
----------------------------
    Description: 
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}
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.
