Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered

[Michael Kun Yang]

Hi,

I really need help, I went through previous posts on the mailing list but
still cannot resolve this problem.

It works when I use local[n] option, but error is occurred when I use
spark://master.local:7077.

I checked the UI, the workers are correctly registered and I set the
SPARK_MEM compatible with my machine.

Best
