Stopping Storm: the right way

From the page that you linked to:

kill

Syntax: storm kill topology-name [-w wait-time-secs]

Kills the topology with the name topology-name. Storm will first deactivate the topology's spouts for the duration of the topology's message timeout to allow all messages currently being processed to finish processing. Storm will then shutdown the workers and clean up their state. You can override the length of time Storm waits between deactivation and shutdown with the -w flag.

As you can see, this is designed to give you a "clean" shutdown. The kill command shuts down the workers.

Command to kill a topology (as you rightly mentioned):

storm kill topology-name

To shutdown the cluster you need to run the following command on each node:

sudo service supervisord stop

Note: give supervisord a few seconds to shutdown all processes. Note that trying to run supervisorctl when supervisord itself is stopped will result in an error message (this appears to be a known user interface issue in supervisord 2.x)

From this documentation

How to kill ALL Storm processes including worker processes? Any worker threads (launched by the Supervisor daemons on the slave nodes) that happen to be running when you are stopping the cluster will continue to run. This is a deliberate design decision of Storm because it means that crashing/restarting Nimbus and Supervisor daemons will not affect any running topologies in Storm. The downside is that you have to put some extra effort into fully stopping all Storm-related processes in a cluster.

If you want to kill ALL processes follow this procedure on the slave nodes:

$ sudo supervisorctl stop storm-supervisor
$ sudo pkill -TERM -u storm -f 'backtype.storm.daemon.worker'

Well if you have started storm as ./storm nimbus & ./storm supervisor & ./storm ui then

after that you may forgot the process id's in that case you can use jps tool to find out pid's then kill them as

$JAVA_HOME/bin/jps

3201 ConsoleConsumer

7528 Jps

2966 Kafka

3680 nimbus

3681 supervisor

6749 Launcher

2669 QuorumPeerMain

killing nimbus first

$ sudo kill 3681

$ sudo kill 3680
