    Description

      Since we have labels on nodes, so we need to track resource usage by labels, includes

      • AM resource (to enforce max-am-resource-by-label after YARN-2637)
      • Used resource (includes AM resource usage)
      • Reserved resource
      • Pending resource
      • Headroom

      Benefits to have such a common class are:

      • Reuse lots of code in different places (Queue/App/User), better maintainability and readability.
      • Can make fine-grained locking (e.g. accessing used resource in a queue doesn't need lock a queue)
