Sorry, I've shaw you my configuration. my configuraion is 5G for
SPARK_EXECUTOR_MEMORY and 5 for spark.task.cpus. In my screenshot, we launch
two tasks on the same machine. Don't you think It's good to offer task memory
twice? My PR gives correct resource management information to mesos' master.
For CPUs, I don't know proper value of executor cpus, but not CPUS_TASK_CPUS.
Recommend this value, please.
