I am getting error after upgrading Ambari from 2.4.3 to 2.5.1

You can try following on the xxx host,

On "xxx" host do the following,

# ambari-agent stop 
# yum remove ambari-agent -y 
# rm -rf /etc/ambari-agent/* 
# rm -rf /var/lib/ambari-agent/* 
# rm -f /usr/sbin/ambari-agent 
# rm -rf /usr/lib/python2.6/site-packages/ambari*
# rm -rf /usr/lib/python2.6/site-packages/resource_management

And now Install the ambari-agent,

# wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.1.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
# yum install -y ambari-agent
# ambari-agent start 

This might solve's your problem.
