Vibha,
For multi-node cluster the main config we need are
nimbus.seeds: ["nimbus_host_name"]
storm.zookeeper.servers:
- "zookeeper_host_name"
- "zookeeper_host_name"
You can look at the example here
https://github.com/apache/storm/blob/master/conf/storm.yaml.example
make sure you copy the same storm.yaml in all the nodes in the
storm cluster.
