We are getting below errors when 15 or 16 spark jobs are running parallelly. We are having a 21 node cluster and running spark on yarn. Regardless of the number of nodes in the cluster does one cluster get to use only 17 ports or is it 17 ports per node in a cluster? How to avoid this when we run 50 or 100 spark jobs parallely?
