Hi,
The docs specify that we can control the amount of ram / cores available via:

-c CORES, --cores CORESTotal CPU cores to allow Spark applications to use on 
the machine (default: all available); only on worker-m MEM, --memory MEMTotal 
amount of memory to allow Spark applications to use on the machine, in a format 
like 1000M or 2G (default: your machine's total RAM minus 1 GB); only on worker
Ommitting these values would cause them to take on defaults. Is there a way of 
"specifying" the default? Or is the only way for it to take on default values 
is to ommit the parameters? Will -c default and -m default work?

Thanks,
Ashic.
