Hitesh Shah commented on TEZ-2212:
----------------------------------
The cleanup call might be better to be done via an event send on the
dispatcher.

> Various components, especially the ones that are made pluggable by TEZ-2003,
> should be informed about DAG completion, so that they can perform required
> cleanup - ContainerLauncher, TaskAttemptListener, Scheduler (already
> informed). In addition ID caches etc should be cleaned up.
