Practical Real-time Data Processing and Analytics

Configuring

As shown in previous screenshot, go to the conf folder and add/edit the following properties in storm.yaml:

• Set the Zookeeper hostname in the Storm configuration:

storm.zookeeper.servers:
- "zkp-1"
- "zkp-2"
- "zkp-3"  

• Set the Zookeeper port:

storm.zookeeper.port: 2182

• Set the Nimbus node host name so that the Storm supervisor can communicate with it:

nimbus.host: "nimbus" 

• Set the Storm local data directory to keep small information such as conf, JARs, and so on:

storm.local.dir: "/usr/local/storm/tmp"

• Set the number of workers that will run on the current supervisor node. It is best practice to use same number of workers as the number of cores in the machine.

supervisor.slots.ports:
    - 6700
    - 6701
    - 6702
 - 6703 ...
