> YARN tests currently try to override YARN's RackResolver, but that class self-initializes
the first time it's called, storing state in static variables and ignoring any further config
params that might override the initial behavior.
> So we need a better solution for Spark tests, so that tests such as {{LocalityPlacementStrategySuite}}
don't flood the DNS server with requests (making the test really slow in certain environments).
