> Set 1)
> "yarn.resourcemanager.monitor.capacity.preemption.total_preemption_per_round"
> should >= 1 / #cluster-nodes. (For example, cluster has 20 nodes,
> total_preemption_per_round should be at least 1 / 20 = 0.05. (By default this
> is 0.1)
> This really should be part of stack-advisor.
> Set 2)
> yarn.resourcemanager.monitor.capacity.preemption.natural_termination_factor =
> 1 (by default is 0.2).
> The two configs will affect preemption for large containers like LLAP. We
> will put these suggestions to documentation, but it will be also good if we
> can update them in Ambari.
