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

             Summary: Non NameNode-HA properties still in hdfs-site.xml causing (at least)
Balancer to fail
                 Key: AMBARI-13946
                 URL: https://issues.apache.org/jira/browse/AMBARI-13946
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.2
         Environment: CentOS6.7, HDP2.3-2950
            Reporter: Benoit Perroud


After enabling NameNode-HA, {{hdfs-site.xml}} does still contain non-HA properties, including

* dfs.namenode.rpc-address
* dfs.namenode.http-address
* dfs.namenode.https-address

This cause the balancer to fail with the following symptoms:

{code}
...
15/11/18 15:48:30 INFO balancer.Balancer: namenodes  = [hdfs://daplab2, hdfs://daplab-rt-11.fri.lan:8020]
...
java.io.IOException: Another Balancer is running..  Exiting ...
{code}

These should be removed from the config.

Steps to reproduce: after turning on NameNode HA, {{grep dfs.namenode.rpc-address /etc/hadoop/conf/hdfs-site.xml}}
shouldn't return anything
