Have a spark cluster setup on a machine with two inets, one public another private. The /etc/hosts file in the cluster has the internal ip of all the other machines in the cluster, like so.
internal_ip FQDN
However when I request a SparkContext via pyspark in YARN client mode(pyspark --master yarn --deploy-mode client), akka binds onto the public ip and thus a time out occurs.

Cluster was provisioned using Ambari(HDP 2.4)
