Subject [jira] [Created] (AMBARI-11780) Ambari creation of oozie/conf/adminusers.txt breaks oozie role seperation for Kerberos

Robert Levas created AMBARI-11780:
-------------------------------------

             Summary: Ambari creation of oozie/conf/adminusers.txt breaks oozie role seperation
for Kerberos
                 Key: AMBARI-11780
                 URL: https://issues.apache.org/jira/browse/AMBARI-11780
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0, 2.0.1, 2.1.0
            Reporter: Robert Levas
            Assignee: Robert Levas
            Priority: Critical
             Fix For: 2.1.0


Oozie restart from Ambari rewrites oozie/conf/adminusers.txt

To support role separation for Kerberos, we need an additional line added to the end of this
file.

The new line is:
{noformat}
oozie-admin
{noformat}

The new file should be generated as:
{code}

oozie
oozie-admin
{code}

#Solution
1. Replace
{code:title=common-services/OOZIE/4.0.0.2.0/package/templates/adminusers.txt.j2}
{{oozie_user}}
{code}
with 
{code:title=common-services/OOZIE/4.0.0.2.0/package/templates/adminusers.txt.j2}
{% if oozie_admin_users %}
{% for oozie_admin_user in oozie_admin_users.split(',') %}
  {{oozie_admin_user}}
{% endfor %}
{% endif %}
{code}

2. Add new property
{code:title=common-services/OOZIE/4.0.0.2.0/configuration/oozie-env.xml}
  <property>
    <name>oozie_admin_users</name>
    <value>oozie, oozie-admin</value>
    <description>Oozie admin users.</description>
  </property>
{code}

3. If the admin user list needs to change when enabling Kerberos, oozie-env/oozie_admin_users
can be set in Oozie's Kerberos descriptor (kerberos.json).
