I'm trying to setup the Ambari agent in each node in my cluster and it works fine for almost all my nodes unless one, when I try to retray the Ambari wizard to fix the problem for this one I get this error:
Running setup agent script...
Command start time 2017-12-01 14:52:13
Server error attempting a GET to /rhsm/ returned status 503
Repository HDP-UTILS-184.108.40.206 is listed more than once in the configuration
sed: can't read /etc/ambari-agent/conf/ambari-agent.ini: No such file or directory
So obviously this error means therer is no ambari-agent installed in this machine,
so I verified if the agent is installed or not with "yum repolist ambari-agent" it replays that the service is already installed:
