> Project: Apache Storm
> Issue Type: Improvement
> Affects Versions: 0.10.0
> Reporter: caofangkun
> Priority: Minor
>
> For now
> if the worker process does not exist any more
> Supervisor will have to wait a few seconds for worker heartbeart timeout and
> restart worker .
> If supervisor knows the worker processid and check if the process exists in
> the sync-processes thread ,may need less time to restart worker.
> 1: record worker process id in the worker local heartbeart
> 2: in supervisor sync-processes ,get process id from worker local heartbeat
> and check if the process exits
> 3: if not restart it immediately
