Thanks, I have previously deployed a few topologies on Storm cluster and Apache 
Mesos cluster (using Storm-Mesos project), however I want to know explicitly 
that if I launched Nimbus through Apache Marathon then how do I launch my 
topology Jar file on Nimbus (since there is no local machine installation of 
Nimbus, it was directly launched through Marathon and Marathon decides which 
machine it should run Nimbus on)?  I have currently Mesos cluster with 10 
nodes, and Marathon on top. Previously I deployed my Storm topology on this 
cluster using Storm-Mesos framework however now I want to use Marathon to 
launch nimbus and my tasks .

Thanks
Obaid

Marathon is a meta-framework, it makes sense to run Storm on Marathon when you 
need to have Storm in a HA mode.

Storm comes up with a command line client:

http://storm.apache.org/documentation/Command-line-client.html

For submitting topology you can use `storm jar ...` command.

There's a configuration file storm.yaml where you can setup various settings, 
anyway the steps should be:

 1) setup ZooKeeper quorum (for testing 1 instance should be enough
 2) distribute storm binary on a cluster
 3) update storm.yaml accordingly
 4) start nimbus (resp. storm-mesos framework - could be done via Marathon, for 
testing purposes starting from console is also fine)
 5) submit topology jar

Nimbus address should be fetched from ZooKeeper, or you could hardcode it into 
storm.yaml.

Thanks a lot Tomas,

I was actually trying out Apache Marathon. I am trying to run storm-mesos 
framework over Marathon.

So far I managed to run Nimbus and UI by running following two commands through 
Marathon UI, however

-          UI dosent know where to find Nimbus.

-          Secondly I don’t know how to deploy my Storm topology jar on running 
instance of Nimbus on Apache Marathon:

Run Numbus on Marathon:
Command: ./storm-mesos-0.9/bin/storm-mesos nimbus
URI: http://downloads.mesosphere.io/storm/storm-mesos-0.9.tgz

Run storm UI on Marathon:
Command: ./storm-mesos-0.9/bin/storm ui
URI: http://downloads.mesosphere.io/storm/storm-mesos-0.9.tgz

It would be great if you could let me know how to deploy Storm topology over 
Marathon. Thanks a lot,

Obaid

Hi Obaid,

you'll need one instance of Nimbus (storm coordinator) which could be running 
as Mesos framework, have a look here:

https://github.com/deric/storm-mesos

Nimbus could be started via marathon, just use something like:

/usr/local/bin/storm-mesos nimbus

Then on Mesos slaves will be launched tasks requested by Nimbus, you don't have 
to start Supervisors on each slave. You could use either some binary
package for distributing Storm jars or it could be copied before launching 
tasks via Mesos.

If you are using Storm DRPC you would need to start DRPC daemon on each node. 
Also for accessing logs from Storm UI there is a log service that
should be running on each node if you would like to use this feature.

Regards,
Tomas

Hi,
Currently, I couldn’t find any tutorial or steps regarding how to launch 
storm-mesos (Storm topology) framework on Apache Marathon. It would be great if 
you guys could give me any reference or hints over how to launch Storm topology 
over Marathon.

-          Do I need to first install Storm on every single machine on my Mesos 
cluster?

-          What is the recommended way to launch Storm topology over Marathon?


Thanks a lot,
Obaid
