Description

I performed an installation using the Ambari GUI and chose to install Nodemanger only on my 4 Datanodes. However, when I do "ps aux | grep nodemanager", I see Nodemanger is running on all 7 of my nodes.
The Ambari GUI reports that 4/4 Nodemangers are running.

Example out put from my Master #1 node:

hadoopvm1-1:/var/lib/ambari-server # ps aux | grep nodemanager
