How to check for port conflicts between HDP and DC/OS cluster if they set up on same set of nodes

[#1]

@Rahul Unnikrishnan

The Following link shows all the default ports used by various HDP components and services. Please check if those ports are being used by any other service to find the conflict.

.

Also use the following command to find the PID that is using any specific port:

# netstat -tnlpa | grep $PORT_IN_ISSUE

Example:
# netstat -tnlpa | grep 50070
