Subject [jira] [Commented] (AMBARI-6652) amabri tries to create local users/groups with a Kerberized cluster
Date Sun, 06 Mar 2016 14:43:40 GMT


Bolke de Bruin commented on AMBARI-6652:

On the MISC tab while creating a cluster (step 7, Customize Services) you can select "Skip
group modifications during install". This actually disables user and group creation entirely.
It is not perfect (ie. no csv, but users are listed). 

I'm trying to figure out if it is possible to launch the creation of centralized users earlier
without too much hassle. At the moment it is assumed user creation needs to be done on the
cluster hosts and obviously when having something like IPA the users need to exist before

>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 1.6.0, trunk, 2.2.0
>            Reporter: Rémy SAISSY
>            Priority: Blocker
>              Labels: kerberos
> 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/
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
