2. Configure Storm

Add the following properties to the /etc/storm/conf.dist/storm.yaml file to configure Storm.

storm.zookeeper.servers:
    - $ZOOKEEPER_SERVERS

nimbus.host: $NIMBUS_HOSTNAME

drpc.servers:
    - "localhost"

storm.local.dir: $STORM_LOCAL_DIR

logviewer.port: 8081

ZOOKEEPER_SERVERS is a comma-separated list of ZooKeeper servers.

NIMBUS_HOSTNAME is the hostname where the Storm Nimbus server is started.

STORM_LOCAL_DIR should be /tmp/storm/local, and it must exist on all Storm nodes.

Execute the following commands:

chown -R storm:storm $STORM_LOCAL_DIR
chmod -R 755 $STORM_LOCAL_DIR
