> The default distribution config {{stratosphere-conf.yaml}} contains keys {{jobmanager.heap.mb}} and {{taskmanager.heap.mb}} for the heap sizes of the JobManager and TaskManager JVMs. If they are not set, {{config.sh}} has default values for them.
> We _always_ use one of these values and set the {{Xms}} and {{Xmx}} properties. After a short discussion with [~rmetzger] and [~StephanEwen] we actually expected that they should not be set if not found in {{stratosphere-conf.yaml}}. This would result in a fall back to the respective JVM default (imho 1/4th of the physical memory since Java 6).
