I'am trying to install CDH Express with CM 5.12.0 on ununtu 16.04. I'am getting this error "Installation failed. Failed to receive heartbeat from agent" I take the following log /var/log/clodera-scm-agent/cloudera-scm-agent.log (please suggest another one if this one does not help you) . I know it is a common problem but I think you can realize what is happend from the log What do you think it is wrong?
