Hi, I have a question about the worker_instances setting and worker_cores setting in aws ec2 cluster. I understand it is a cluster and the default setting in the cluster is
*SPARK_WORKER_CORES = 8 SPARK_WORKER_INSTANCES = 1* However after I changed it to *SPARK_WORKER_CORES = 8 SPARK_WORKER_INSTANCES = 8* Seems the speed doesn't change very much. Could anyone give an explanation about this? Maybe more details about work_cores vs worker_instances? Thanks a lot!
