These are some notes to bear in mind when deploying AXA 17.3 relating to host resolution
Release : 17.3
Component : APP EXPERIENCE ANALYTICS ENGINE
Check /etc/hosts and /etc/hostname on each machine and compare IP address resolution to ifcfonfig and ip addr on each one. Check if there are differences in upper or lower case, the installer process checks are case sensitive.
Check if dnslookup is enabled - if not, the installer will complain about hostnames. This does not break the install
Do not use spaces, underscores or other such characters in hostnames
Check the hostnames to be used with command 'hostname' and make sure they are present in /etc/hosts -files for each node.
Fully qualified domain name (FQDN) is needed by the installer as the first hostname after IP Address in /etc/hosts
The hostname used is the first resolved hostname in /etc/hosts. Example: FQDN FIRST otherwise the jarvis installer fails with many "no such file" - note that install script uses 'nslookup' to verify hostname or IP Address
