      Description

      Knowing only the "available", "used" resource is not enough for YARN management tools like auto-scaler. It would be helpful to diagnose the cluster resource utilization if it gets "Pending Resource" from RM RESTful APIs. In a certain extent, it represents how starving the applications are.

      Initially, we can add "pending resource" information in below two RM REST APIs:

      RMnode:port/ws/v1/cluster/metrics
      RMnode:port/ws/v1/cluster/nodes
