On each host running an Ambari Agent, stop the Ambari Agent:

ambari-agent stop

Edit the Ambari Agent properties file:

vi /etc/ambari-agent/conf/ambari-agent.ini

In the [agent] section, modify the piddir and logdir properties:

[agent]

logdir=/var/log/ambari-agent

piddir=/var/run/ambari-agent

Save the file.

Create the new directories and be sure to set the directory ownership and permissions to allow the Ambari Agent process access.

Restart the Ambari Agent.

ambari-agent start
