Does MapR need mDNS?

I am hardening a MapR platform and based on a security scan, there is a vulnerability called "mDNS detection" with suggested resolution to filter incoming traffic to UDP port 5353. Does MapR use the mDNS and how will it impact the MapR platform if the resolution to filter traffic to port 5353 is followed? Thank you.
