> If a framework already has an executor placed on a machine, it may be able to use an offer that contains no or almost no memory but includes cpus. The current allocator will never make such offers. 
> This can lead to non-intuitive results: If one runs Spark against Mesos configuring Spark to use almost exactly the available-to-Mesos memory, Spark will start running but eventually stall.
