--------------------------------

             Summary: hadoop.security.auth_to_local in core-site is overwritten to null when installing new service to a secure cluster
                 Key: AMBARI-9098
                 URL: https://issues.apache.org/jira/browse/AMBARI-9098
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent, ambari-server
    Affects Versions: 2.0.0, 2.1.0
            Reporter: Jimmy Da


1. Setup secure HDFS cluster with services (HDFS, MR2, YARN, ZooKeeper) and Kerberos
2. Configure secure user for Oozie (or any other secure service) - create user+setup keytab
3. Install Oozie via Ambari UI --> FAIL
    FATAL namenode.NameNode (NameNode.java:main(1400)) - Exception in namenode join
    java.lang.IllegalArgumentException: Invalid rule: null
4. Check hadoop.security.auth_to_local property in HDFS configurations under Advanced core-site, see null instead of "RULE:..."
---------------------------------------------
The core-site overwrite is happening in ambari-server/src/main/resources/stacks/HDP/2.0.6/hooks/after-INSTALL/scripts/shared_initialization.py, when I commented out the lines, it works again, but I'm sure there's a reason the check and rewrite is there

Thanks!
