+  hdp_mon_ganglia_addons-0.0.1-2.noarch.rpm and hdp_mon_nagios_addons-0.0.1-2.noarch.rpm on the hosts running 
+  Ganglia and Nagios server, respectively, to make your changes effective.
+  After your Hadoop cluster is installed using Ambari, go to the host(s) running Nagios and Ganglia server, 
+  remove these pre-installed addon RPMs for Nagios and Ganglia, and install the new ones built from the source.
