Problem with Cloudera agent installation on CDP Private Cloud

Hi,

we have a problem with agent installation on hosts which we want to add to the cluster.

On the Install Agents page, the process fails with an error "Failed to copy installation files.

Examining cloudera-scm-server.log we got this (The process fails when trying to copy files).

On the node where the agent should be installed (auth.log). The ssh connection opens and authenticates, but it disconnects a second later.

What could be the issue here? We are using ubuntu 20.04.4 servers, cloudera manager 7.4.4, and CDP private cloud base 7.1.7.

On the same configuration the agent installation was successful with Cloudera manager 7.5.4 and CPD private cloud base 7.1.7, but it failed when installing parcels. We have later found out that for ubuntu 20.04 those versions are not compatible, so we have rebuilt the cluster.

Thank you for your reply.

@asomrak ,

Please have a look at the individual nodes and look for a directory called /tmp/scm_prepare_node.*

Inside that directory there should be a log file called scm_prepare_node.log, which could tell you more about the error.

If you can't figure out the root cause from that log's content, please share the file here so that we can take a look.

Cheers,

André

HI,

thank you for your reply. I have found the solution.

The problem was related to one of the known issues of Cloudera manager 7.4.4:

OPSAPS-61523

Failure when installing Cloudera Manager AgentsWhen installing the Cloudera Manager Agent package on new hosts through either the Add Hosts wizard or Add Cluster wizard, if you select Cloudera Repository during the Select Repository step, the Agent Installation fails with message "Failed to Copy Installation Files".Select Custom Repository instead and enter the URL and your license credentials in the following format:
