The design was to leave space to handle more than one cluster at a time in a single Ambari Server instance. Maybe Ambari could have a convenient resource /api/v1/cluster (like you mention) that will convert to the [0] cluster automatically? If that makes sense, maybe file that JIRA in Ambari project?

Can you post the tail of ambari-server.log? Likely an exception in there

There is also an Ambari project wiki page on using the Ambari API for Kerberos: https://cwiki.apache.org/confluence/display/AMBARI/Automated+Kerberizaton

In case you want to perform this via the UI, the docs for enabling Kerberos via Ambari can be found here: http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Ambari_Security_Guide/content/ch_configuring_amb_hdp_for_kerberos.html Including a section on setting up an MIT KDC: http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Ambari_Security_Guide/content/_optional_install_a_new_mit_kdc.html

FWIW, There is API info on how to determine and restart host components on a given host. https://cwiki.apache.org/confluence/display/AMBARI/Restart+Host+Components And this is the JIRA for Ambari to support auto-start of services + components: https://issues.apache.org/jira/browse/AMBARI-2330

I think that message is meant to be more "INFO" than "WARNING". It's checking if there is a previous ambari-env.sh.rpmsave file that was created already and letting you know since there is none, there is are no old env settings to merge. Looks like it has been changed to INFO (in future Ambari release) to avoid potential concern. https://github.com/apache/ambari/commit/a5807823299cc575e8269167a6c0f45b003bb60c
