Add the following properties to the /etc/storm/conf/storm.yaml file, substituting your own list of hostnames and ports:

storm.zookeeper.servers: [<zookeeper-servers>]              
nimbus.seeds: [<nimbus-hostnames>]
storm.local.dir: $STORM_LOCAL_DIR
logviewer.port: 8081
storm.log.dir: $STORM_LOG_DIR   

where:

<zookeeper-servers> is a comma-separated list of ZooKeeper servers.

<nimbus-hostnames> is a comma-separated list of hosts where the Storm Nimbus server is started.

$STORM_LOCAL_DIR and $STORM_LOG_DIR must exist on all Storm nodes.

For example:

storm.zookeeper.servers: ["host1:port1", "host2:port2", "host3:port3"]
nimbus.seeds: ["host1:port1", "host2:port2"]
storm.local.dir: /mnt/storm
logviewer.port: 8081
storm.log.dir: /var/log/storm

Run the following commands:

chown -R storm:storm $STORM_LOCAL_DIR $STORM_LOG_DIR

chmod -R 755 $STORM_LOCAL_DIR
