Description

When attempting to add any custom service to ambari  (user group management on) the following error occurs:

KeyError: u'serviceuser'

or example:

KeyError: u'flink'

A current bulky work around is a python to disable user group management:

python /var/lib/ambari-server/resources/scripts/configs.py -u admin -p admin -n DDP -l hdp.dfheinz.com -t 8080 -a set -c cluster-env -k  ignore_groupsusers_create -v true

 I have tried to find a source of the users in ambari metastore, as well as proper/correct source code in the custom service fileset to add/create the user:group requirements.  I have not been successful.

I am currently working on a seamless install of HDP with 3 different Third party services and this is a blocker to this solution.
