Hortonworks provided package: ambari-agent 4.2.0.1-1
Description
Using the following config (unchanged from a previous install, so missing options relevant to 2.4.0.1) with ambari-agent 2.4.0.1 causes the ambari-agent script to chown the entire filesystem as root.

It looks like the following lines are to blame
ambari-sudo.sh chown -R $current_user "$AMBARI_PID_DIR/"
ambari-sudo.sh mkdir -p "$AMBARI_AGENT_LOG_DIR"
ambari-sudo.sh chown -R $current_user:$current_group "$AMBARI_AGENT_LOG_DIR/"
No checking for unset variables in 2016? Top notch.
