    Description

      Ephemeral port static allocation requires fixed limit of containers per host. This is not exposed to frameworks so they will receive TASK_LOST notifications without the ability to proactively control this or react accordingly.

      By exposing the ephemeral port ranges assigned to containers as a resource, frameworks can potentially fit more containers per host, but also won't receive offers for slaves that can't run any more tasks due to hitting the limit.
