Paul Yang created HIVE-12865:
--------------------------------
Summary: Exchange partition does not show inputs field for
post/pre execute hooks
Key: HIVE-12865
URL: https://issues.apache.org/jira/browse/HIVE-12865
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 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, the read entity field is empty.
This is an important issue as the hook interface may be configured to perform
critical warehouse operations.
