After update of mapr-setup script and other features, we tried to install 7.4 and 7.3 version of data fabric. We get the issue below;
Is it about the 7.4 and 7.3 issue or something else? How can we fix it?
Solved! Go to Solution.

SolutionHi @msaidbilgehan,
This is likely caused by not using FQDNs, I saw your other post which had node-0.cluster but it's 'node-0' here. Please ensure "node-0.cluster" resolves to the same IP as "node-0" (and same for other nodes), then use the node-0.cluster etc names in the installer. This is mentioned in the docs at https://docs.ezmeral.hpe.com/datafabric-customer-managed/73/AdvancedInstallation/PreparingEachNode-connectivity.html.
Regards,
Laurence Darby

Re: Data Fabric Installation Issue About Generating SSL Key
Thank you for your response. We missed the naming. Btw, we add the domain name after the hostname such as "node-1.company.com" but is there anything we should do more than the naming? Because devices are not logged in the DNS server. I am not a network guy so not sure about what we need to do for this kind of naming if there is a problem occurs.

Re: Data Fabric Installation Issue About Generating SSL Key
All the hostname must be resolvable, ie; node-1.company.com should be mapped to a valid IP address and vice versa. There is no need to have DNS entries for name resolution, it can be done by updating /etc/hosts file (on all nodes). [ As you may know, it'd be difficult to maintain the hosts file as number of nodes grow, so it's better to go with DNS in large clusters].
Also make sure to use the hostname while using installer/'running configure.sh' tool.
