does spark needs dedicated machines to run on

[Shams ul Haque]

Hi,

I have developed a spark realtime app and started spark-standalone on my
laptop. But when i tried to submit that app in Spark it is always
in WAITING state & Cores is always Zero.

I have set:
export SPARK_WORKER_CORES="2"
export SPARK_EXECUTOR_CORES="1"

in spark-env.sh, but still nothing happend. And same log entry in:
*TaskSchedulerImpl:70 - Initial job has not accepted any resources*

So, does i need a seperate machine for all this?

Please help me to sort that out.

Thanks
Shams
