Description

With a Kerberized cluster (using FreeIPA from CentOS 6.4 in my case), it is impossible to install/start services using Ambari.

The cause is that Ambari (the hooks/before-INSTALL/scripts/shared_initialization.py::setup_users()) checks and creates users and groups as if there were no Kerberos.

• check /etc/passwd and /etc/groups
• use adduser, groupadd, usermod, groupmod

It would be better to either :

• add a dialog in Ambari to choose the CLI tools for dealing with users/groups check and creation

• disable the check/creation and inform the end user of the users/groups that are required / generate a csv if needed
