-------------------------------
Summary: Add a new hook triggers before query compilation and
after query execution
Key: HIVE-14340
URL: https://issues.apache.org/jira/browse/HIVE-14340
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 2.2.0
Reporter: Chao Sun
Assignee: Chao Sun
In some cases we may need to have a hook that activates before a query
compilation and after its execution. For instance, dynamically generate a UDF
specifically for the running query and clean up the resource after the query is
done. The current hooks only covers pre & post semantic analysis, pre & post
query execution, which doesn't fit the requirement.
