> The current default of spark.yarn.scheduler.heartbeat.interval-ms is 5
> seconds. This is really long. For reference, the MR equivalent is 1 second.
> To avoid noise and unnecessary communication, we could have a fast rate for
> when we're waiting for executors and a slow rate for when we're just
> heartbeating.
