      • mapreduce.cluster.administrators
      • mapreduce.cluster.acls.enabled (enabled by default)
      • mapreduce.job.acl-modify-job
      • mapreduce.job.acl-view-jo
  • Update the YARN properties.
    • In the Ambari UI, navigate to YARN service > Configs.
    • Add the HDFS user to:
      • yarn.admin.acl
  • Restart the Pulse service.
    • Restart the ad-connector service on the Pulse Master to apply the changes.

Result
