How do I to set the number of slots?

[MitchBit]

I'd like to assure, that each bolt/spout runs on a dedicated machine and therefore I'd like to set the number of slots to exactely 1 per machine.

Would be great, if somebody could let me know, how to achieve this.

Forgot to mention:
I've tried to set the storm.yaml like follows using only a single port, but still, when for instance rebalancing the topology, two CPU-heavy tasks are put on a single machine. I thought storm.yaml would override the default.yaml.

supervisor.slots.ports:
   - 6700

A hint is well appreciated!

HI,  MitchBit . You can develop a pluggable scheduler.

The slots on each machine is determined by the storm.yaml that the supervisor has, not the storm.yaml on your machine or the topology config. You have to restart the supervisor for it to pick up any changes.

So the storm.yaml on nimbus doesn't affect the number of slots at each worker?

So I need to touch every worker machine, run stop.sh, update the storm/conf/storm.yaml file and add

supervisor.slots.ports:
   - 6700

and run start.sh again?

What am I doing wrong because it does not produce the desired effect - UI still lists the machine with 4 slots...

sorry for this mess - I had a small typo  and now it works wonderfully - thanks nathan!
