Hello!
There is no such a restriction. In storm.yaml you have the
storm.zookeeper.servers section:
storm.zookeeper.servers:
- "server1"
- "server2"
Here you can configure your zookeper cluster. If you are using Amazon EC2,
a good start for testing Storm in cloud, is Kasper' Madsen project
https://github.com/KasperMadsen/storm-deploy-alternative
The default configuration creates a VM with one single zookeper cluster
that is outside the Storm cluster. Please have a look.
I have used too and it was really helpful.
Hope that these help.
Best regards,
Florin
