> Decouple driver and executor heartbeat intervals. Due to sampling frequencies in memory metric reporting intervals we do not have a 100% accurate view of stats at drivers and executors. This is particularly observed at the driver, where we don't have the benefit of a larger sample size of metrics from N executors in application. We should provide a way to increase the rate of collection of metrics at the driver, to aid in overcoming the sampling problem, without requiring users to also increase executor heartbeat frequencies.
