Let us see how we can add the new node as a worker to the cluster.
- Worker Components:
- HDFS Datanode
- YARN Node Manager
- HBase Region Server
- Impala Impalad
- To add a node as HDFS Datanode, we need to have additional storage devices mounted and formatted.

- Once the node is formatted, either we can use Host Template or add each and every worker component manually.
