we have ambari cluster machines , HDP - 2.6.X we want to know the opinion of hortonworks about the avahi service dose this service should be disable or enable on ambari cluster machines ( master / workers / kafka ) ? note - we want to disable this service especially on the data-node machines ( workers ) , because we think that this service could be the reason of OS restart , for now this service is enable and running on all our machines in the ambari cluster reference - https://www.systutorials.com/docs/linux/man/8-avahi-daemon/ service avahi-daemon status Redirecting to /bin/systemctl status avahi-daemon.service ● avahi-daemon.service - Avahi mDNS/DNS-SD Stack Loaded: loaded (/usr/lib/systemd/system/avahi-daemon.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2018-04-25 18:52:11 UTC; 17min ago ...
