Subject [jira] Created: (HIVE-2027) Asynchronous Hooks
Date Thu, 03 Mar 2011 17:58:40 GMT
Asynchronous Hooks
------------------

                 Key: HIVE-2027
                 URL: https://issues.apache.org/jira/browse/HIVE-2027
             Project: Hive
          Issue Type: New Feature
            Reporter: Ning Zhang


PreHook and PostHook are executed sequentially in the order if they are defined in hive.exec.pre.hooks
and hve.exec.post.hooks. In some cases the sequential semantics are mandatory, but not for
all cases. It would be desirable to define an AysncHook that extends Hook (similarly for AsyncPreHook
and AsyncPostHook) to asynchronously execute the hooks in a thread pool.
