Ubuntu 18.04 is now supported with CDH 6.2 release, see Release Notes

Sure! The data of the two timeseries databases would have to be merged. Technically this is possible but there is no code in Cloudera Manager to do it, as this is not an intended use case.

Hi raphaelt, not it's not possible to merge the two directories. You need to make a decision with which folder to proceed, thus where to have gaps in the charts in CM.

Can you kinit using this principal and then run hdfs commands like "hdfs dfs -l /"? Does this work?

If the server crashed with OOM then it may not be sufficiently staffed with resources (RAM). Are you installing to a single node? What are the hardware resources for this host? Please make sure that the YARN service is started up and in good health state before starting Oozie. The HDFS startup error indicates communication issue to CM server, please review the CM server logs if there are any issues shown during this time including Detected pause in JVM messages.

The kerberos ticket is valid but the DN complains about Wrong principal in request Please review your application configuration or proxy software for correct kerberos principal configured. As you upgraded your proxy server host, may it be that some settings changed like hostname or krb5.conf? Another possibility is that there is a mismatch of encryption types, see this KB article

Happy to hear the issue is resolved! Just for completeness, did you delete /var/lib/cloudera-scm-agent/cm_guid on the cluster nodes?

Please check for errors in the Event Server logs and stderr/stdout logs. Also check /var/log/messages if it may have been killed by the kernel oom killer.

As @Consult mentioned, you can use the Cloudera Navigator UI to query for Hive audit events, in the Audits tab. Each audit event is associated with the username and the IP address of the client request. This should help you to get an idea of who runs the most queries.

No web services need to be running to access the Cloudera Manager API, just Cloudera Manager needs to be up and running. Please find instructions how to use the CM API in Cloudera Manager API documentation chapter.
