Now that I think more about this, I guess that Unable to connect to: https://hadoop-m:8441/agent/v1/register/hadoop-m.c.hdp-1-163209.internal started to occur when ambari server started to throw NPEs, which I detected right after (re)starting it, which I did right after I copied HUE to ambari's stack with: sudo git clone https://github.com/EsharEditor/ambari-hue-service.git /var/lib/ambari-server/resources/stacks/HDP/$VERSION/services/HUE (which are the very first steps of HUE installation guide via ambari). Regarding FQDNs, connectivity ambari server <-> ambari agents and handshake/registration ports (8440/8441). @hadoop-m $ more /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain610.132.0.4 hadoop-m.c.hdp-1-163209.internal hadoop-m # Added by Google 169.254.169.254 metadata.google.internal # Added by Google $ hostname -f hadoop-m.c.hdp-1-163209.internal @hadoop-w-0 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.132.0.2 hadoop-w-0.c.hdp-1-163209.internal hadoop-w-0 # Added by Google 169.254.169.254 metadata.google.internal # Added by Google $ hostname -f hadoop-w-0.c.hdp-1-163209.internal $ telnet hadoop-m 8440 Trying 10.132.0.4...
