Subject [jira] [Commented] (AMBARI-8610) Kerberos add hosts/services CSV required for automating keytab distribution
Date Thu, 18 Dec 2014 12:29:13 GMT


Hari Sekhon commented on AMBARI-8610:

This should also be extended to handle adding new service components such as for RM HA, see
AMBARI-8785 for example. Iirc I also had that issue when adding ZooKeepers.

> Ambari generates a CSV list of principals for generating keytabs only when initially
kerberizing a cluster.
> However, when adding nodes to the cluster Ambari provides no such CSV or list of principals
- leaving the user to figure out the list of required principals and keytabs themselves.
> A CSV of new principals and keytabs should be created whenever deploying new hosts or
new services to an existing kerberized cluster to allow for similar automation of extending
an existing cluster.
> I use the original CSV as input to a perl program I've written to automate kerberos principal
creation, keytab exports and distribution to nodes based for a FreeIPA realm (standalone MIT
KDC as per stock is used more for small VM / PoC setups without LDAP integrated
users and groups).
> If anyone else wants to automate FreeIPA Kerberos keytabs for their clusters they can
use this program on my github:
> {code}
> git clone
> cd toolbox
> make
> ./ --help
> {code}
