Cluster creation issue with Ambari agent

[#1]

While trying to create a single node cluster with Ambari server installed on it I am facing the following problems:

a) Using a wizard I am stuck at 'Confirm Hosts' page where status and progress bar are not changing.

b) When trying to manually install Ambari Agent an exception pointing to a Controller Register method is thrown (line 377). Config in the ambary-agent.ini points to the same host that I get from 'hostname -f'

ambari-agent.out

@mertez will recommend to re-install after cleaning the old installation.

yum remove ambari-agent
rm -rf /var/lib/ambari-agent
rm -rf /var/run/ambari-agent
rm -rf /usr/lib/amrbari-agent
rm /etc/yum.repos.d/ambari.repo
yum clean all
wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.1.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
yum install ambari-agent

Pankaj thanks for your help. The problem was in using ambari-server 2.4.1 and ambari-agent 2.2.1. After the upgrade the issue was gone.

First problem was solved by modifying the ambari user in ambari.properties.
