In Kubernetes/Spark, we see fairly similar behavior in the scenario
described. When the simultaneous container launching is not throttled, it is
capable of DOSing the system. Our solution so far is to allocate in rounds
(similar to the throttling mechanism proposed here), and to wait for readiness
of previously launched containers (registration of those executors) before
proceeding.
