  1. For a secure Hadoop cluster, the beehive user must be defined on all nodes managed by YARN.
  2. To verify all nodes managed by YARN, issue the yarn node --list --all command. The output of the command should list all worker nodes, and indicate 0 for all nodes when the Aster instance or any other YARN application is not up and running. For example:
    # yarn node --list --all
