Description
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.
