Add Host as Worker

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.
