Will check if I have new version of the upgrade document.  There won't be much changes other than the target files, the upgrade is preety easy unless if you have very complex cluster.    How big and complex is your cluster ? HA / Non HA  ? And Are you going by packages/Parcels ?    Will be happy to help if you have any more questions.    Thanks  -Bharat ... View more

go to /var/lib/cloudera-scm-agent/ and remove all the 3 files (uuid, cm_guid, response.avro)  stop the  cloudera-manager-agent and remove this host details from "/etc/hosts" for all other nodes . This should solve the problem, let us know if still any issues.    Thanks  -Bharat ... View more

Current release is 5.14.2 , best practices is select n-1 (where n is the latest)  Using Parcels is mostly recommended. Refer the attached Upgrade document.    Thanks  -Bharat           ... View more
