Everytime we submit a job to YARN, it opens up a new port, it is hard to setup a firewall rule. As there is a need enforcing the security policies in cluster, is there any way to have a port range ApplicationMaster in YARN?
What is the best practices interms of setting up firewall in the cluster?
I'm using CDH enterprise 5.10
Thanks in advance
