If each node of your cluster doesn't recognize to each other by local hostname of the node, you need to set storm.local.hostname to IP address for each node's storm.yaml config file.
We occasionally add pairs of local hostname / IP to /etc/hosts of all nodes, or register servers to private DNS when available.
