-------------------------------

             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.
