> YARN-5540 introduced some optimizations to remove satisfied SchedulerKeys from the AppScheduleingInfo. It looks like after YARN-6040, ScedulerRequestKeys are removed only if the Application sends a 0 numContainers requests. While earlier, the outstanding schedulerKeys were also remove as soon as a container is allocated as well.
> An additional optimization we were hoping to include is to remove the ResourceRequests itself once the numContainers == 0, since we see in our clusters that the RM heap space consumption increases drastically due to a large number of ResourceRequests with 0 num containers.
