When I add Service Node with non-root user (but with root privileges), I got the following error:
Command 'python yum_deploy.py ' execution failed with following error: 'sudo: cd: command not found python: can't open file 'yum_deploy.py': [Errno 2] No such file or directory'
Internal issue with ID #430 in PPA. It will be fixed in PPA 11.5 MU #2.
Add the Service Node with user 'root' or update PPA 11.5 to MU #2
