CDP trial adding clusters failing

Cluster manager looks fine

Ubuntu 20.04, bare metal host. No SElinux, no firewall

The agent log says

BEGIN sudo dpkg -l openjdk8 | grep -E '^ii[[:space:]]*openjdk8[[:space:]]*'
dpkg-query: no packages found matching openjdk8
END (1)
BEGIN sudo apt-cache show openjdk8
E: No packages found

___________

If you skip JDK installation in the wizard, it fails with

BEGIN sudo dpkg -l cloudera-manager-agent | grep -E '^ii[[:space:]]*cloudera-manager-agent[[:space:]]*'
dpkg-query: no packages found matching cloudera-manager-agent

 

Any clues?

Thanks for all the input.

We reinstalled ubuntu 20.04 and started fresh. It failed again but this time the log showed that curl was missing on the machine. Manually installed curl and basically monitored the logs in /var/tmp for the nodes to push along any small issues. Finally we got the cluster installed. However, it still had some health monitoring and inconsistencies when installing services.

 

Finally, we dropped Ubuntu and went with centOS 7. Had better luck with that, the errors were more manageable. Anyone going though this I think Ubuntu 20.04 cluster scripts/error messages are a bit immature, go with RHEL if you can.

Also, take any health warning reported by the cloduera manager seriously like "swappiness". They are "Warnings" but will save you a ton of time if addressed ahead of time.

@aval Can you tell me which doc you are following and are you adding 2nd cluster in the same CM? There should be repo file in this location.
