I have a question.

How do I selectively open port range for Hadoop Yarn App Master on a cluster.

I have seen the jira issue in
fixed in version 0.23.2 and accordingly downloaded the latest version

I have added the following property in mapred-site.xml

and accordingly opened the port range 50100-50200 in iptables.

After submitting the hadoop job it is using the port 50100 but it is
also using one ephemeral port for IPC server.
I have noticed different ephemeral ports used for IPC server for each
job submission.

Pl let me know what property can be set to restrict this random port used.
