      Description

      During Upgrade

      1. If cluster is big i.e >50GB and each machines has minimum 10GB resources
        • If yarn-system queue doesn't exist then we shall create a queue with zero capacity.
        • All the necessary setting for queue such as queue-priority, queue-acls, disabling pre-emption for this queue are set.
        • ats-hbase app queue name also set to yarn-system
        • But do NOT enable system service mode by default. Let upgrade happens in embedded mode successfully.
        • Post upgrade, admin can change flag to enable system_service mode if required by providing sufficient capacity to yarn-system queue. This step need to be documented.
      2. If cluster is small
        • Continue upgrade in embedded mode without creating a yarn-system queue.
