Description

Currently there are limitations to running multiple Ambari Agents on the same host because it uses a single path for

/etc/ambari-agent/conf/ambari-agent.ini
/var/run/ambari-agent/ambari-agent.pid
/var/lib/ambari-agent/data
/var/log/ambari-agent/

Ambari Agent already has a way to change the port, log dir, and pid dir through its config file, so we also need it to support its own unique home directory with its own unique config file.

Furthermore, the agent will have to override its hostname.
