On the agent host do the following first? Then try again:

yum remove ambari-agent -y
rm -rf /etc/ambari-agent/*
rm -rf /var/lib/ambari-agent/*
rm -f /usr/sbin/ambari*
rm -f /usr/lib/python2.6/site-packages/ambari_commons
rm -rf /usr/lib/python2.6/site-packages/resource_management
rm -rf /usr/lib/python2.6/site-packages/ambari_jinja2

And then try installing agent from ambari UI. Or manually install the agent as following:

wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
yum install ambari-agent -y

.

you shoul either use ssh (id_rsa) or install ambari-agent on all hosts

after ambari agent is installed (change the /etc/ambari-agent/conf/ambari-agent.ini ) and set the hostname of ambari-server machine for all machines

then change the /etc/hosts file ( ip_of_machine1 name_of_machine1

ip_of_machine2 name_of_machine2....)

then ==> ambari-agent restart for all machines
