> Key: STORM-3355
> URL: https://issues.apache.org/jira/browse/STORM-3355
> Project: Apache Storm
> Issue Type: Improvement
> Affects Versions: 2.0.0
> Reporter: Stig Rohde Døssing
> Priority: Minor
> Labels: pull-request-available
>
> We currently have the supervisor.worker.shutdown.sleep.secs parameter
> allowing users to specify how long the supervisor should wait between
> starting the initial graceful shutdown of a worker, and sending the followup
> force kill.
> When workers are asked to shut down gracefully, they run a shutdown hook that
> allows 1 second of cleanup, before force halting the JVM. I think it would be
> good to make the delay between starting the shutdown hook and halting the JVM
> follow the same config as in the supervisor.
> I don't see why it is useful to specify the force kill delay in the
> supervisor, if the worker just suicides after one second anyway. Letting the
> user configure how long shutdown is allowed to take lets them make use of the
> bolt's cleanup method for cleaning up resources in non-crash scenarios.
> Use case here
