> Key: STORM-183
> URL: https://issues.apache.org/jira/browse/STORM-183
> Project: Apache Storm
> Issue Type: Bug
> Reporter: caofangkun
> Assignee: Parth Brahmbhatt
> Priority: Minor
> Fix For: 0.9.3
>
> Attachments: STORM-183-1.patch
>
>
> if the process is killed forcefully from the OS or if it's crashing due to
> resource issues (e.g., out of memory), shutdown hooks won't be invoked.
> -TERM (15)
> The process is requested to stop running; it should try to exit cleanly
> -KILL (9)
> The process will be killed by the kernel; this signal cannot be ignored.
> So should we better use 'kill -15' ?
> See:
> https://github.com/apache/incubator-storm/blob/master/storm-core/src/clj/backtype/storm/util.clj#L392
> https://github.com/apache/incubator-storm/blob/master/storm-core/src/clj/backtype/storm/daemon/supervisor.clj#L175
> will never be called for supervisor:
> https://github.com/apache/incubator-storm/blob/master/storm-core/src/clj/backtype/storm/daemon/supervisor.clj#L396
> will never be called for worker:
> https://github.com/apache/incubator-storm/blob/master/storm-core/src/clj/backtype/storm/daemon/worker.clj#L421
> We'd better add something like :
> (.addShutdownHook (Runtime/getRuntime) (Thread. (fn [] (.shutdown mk-sv))))))
> ?
