By default most UI address (for hdfs datanode, yarn nodemanager, etc) are started on http://<hostname's fqdn>:port (50075, 8042, etc).
I do not achieve to change the default server name... which is important to me for I'd like to expose these ports to an all users network and restrict internal communication to a dedicated one... I unsuccessully tried to change yarn.nodemanager.webapp.address to alter the hostname... I also tried to play with public_hostname.sh to define a public hostname but webservers don't seem to start on it?
Did someone already achieve to do this ?
