> Key: STORM-1667
> URL: https://issues.apache.org/jira/browse/STORM-1667
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.0
> Reporter: Zhuo Liu
> Assignee: Zhuo Liu
> Fix For: 1.0.0
>
>
> There is a race condition since shutdown-worker is called by both
> sync-processes and synchronize-supervisor in supervisor. One pid directory
> might have been already deleted when rmr-as-user tries to delete it.
> Therefore, we should not let the FileNotFoundException get thrown and crash
> the supervisor.
