             Summary: KeyError when Adding Custom Ambari Service
                 Key: AMBARI-25522
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-web
    Affects Versions: 2.7.5
            Reporter: Steven Matison

When attempting to add any custom service to ambari  (user group management on) 
the following error occurs:
KeyError: u'serviceuser'{noformat}
or example:
KeyError: u'flink'{noformat}
A current bulky work around is a python to disable user group management:
python /var/lib/ambari-server/resources/scripts/ -u admin -p admin -n 
DDP -l -t 8080 -a set -c cluster-env -k  
ignore_groupsusers_create -v true{code}
 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.
