I'm trying to install a Cluster (CDH 5.3) using CM-Wizard.
I got the following erroe message:
( self.log_heartbeat_exception("Heartbeating to %s:%s failed.)
AttributeError: 'Agent' object has no attribute 'master_port'
Do you have an idea or a solution to solve this issue?
Thanks and Regards,

If you receive this message, chances are that you have not specified the port in your agent configuration.
In file /etc/cloudera-scm-agent/config.ini you should have the following line:
server_host=Cloudera Manager host name or ip goes here
The bolded line is likely missing.
If it's there, there are numerous rather obscure things that might be wrong.
Sometimes a combination of these can cause what looks like an impossible situation.
