             Summary: Ambari does not update ha.zookeeper.quorum property in core-site.xml file even if there are more than 3 ZooKeeper servers configured via Ambari.
                 Key: AMBARI-7217
                 URL: https://issues.apache.org/jira/browse/AMBARI-7217
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 1.7.0
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
             Fix For: 1.7.0


PROBLEM:  Ambari does not update ha.zookeeper.quorum property in core-site.xml even if there are more than 3 ZooKeeper servers configured via Ambari.

BUSINESS IMPACT: NA

STEPS TO REPRODUCE:  
1. Add the 2 ZooKeeper servers to an existing cluster that is already running 3 ZooKeeper servers.
2. You will now see a total of 5 ZooKeeper servers running from the Ambari UI.
3. Open up the /etc/hadoop/conf/core-site.xml file.
4. You will observe that there are only entries for the 3 ZooKeeper services in ha.zookeeper.quorum and is not updated with the newly added ZooKeeper services.

ACTUAL BEHAVIOR:  Ambari allows adding new ZooKeeper services but does not update them accordingly ha.zookeeper.quorum property in core-site.xml
 
EXPECTED BEHAVIOR: Ambari should update core-site.xml appropriately whenever a new ZooKeeper server is added. 

SUPPORT ANALYSIS:  Reproduced the issue.
