Hi all,
I am a DevOps guy and I need implement a storm cluster with the
proper start and stop init scripts on a Linux server. I already went through
the documentation and it seems simple enough. I am using supervisor as my
process manager. I am however having a debate with one of the developers using
Storm on the proper way to shutdown Storm and I am hoping that you fine folks
can help us out in this regard.
The developer believes that before you tell supervisor to kill
(SIGTERM) the storm workers, supervisor, and nimbus, you must first issue a
"storm deactivate topology-name", then tell supervisor to kill all the various
processes. He believes this because he doesn't know if Storm will do an
orderly shutdown on SIGTERM and that there is a chance that something will get
screwed up. This also means that when you start storm, after nimbus is up, you
need to issue a ""storm activate topology-name".
I am of the belief that because of storms fast fail and because
it guarantees data processing, none of that is necessary and that you can just
tell supervisor to stop the process.
So who is right here?
