      Description

      Job may be stuck for reasons such as:

      • hitting queue capacity
      • hitting user-limit,
      • hitting AM-resource-percentage

      The first queueCapacity is already shown on the UI.
      We may surface things like:

      • what is user's current usage and user-limit;
      • what is the AM resource usage and limit;
      • what is the application's current HeadRoom;
