-----------------------------
    Description: 
Condition:
1. hdfs deploy ha
2. "dfs.namenode.http-address" is not set to the default port 50070

Result:
1. Ambari will always substitute configures relative to "nn2"
2. The active "Move Namenode" failed and make configure inconsistent, the cluster crashes

Code location:
{code:title=ambari-web/app/controllers/main/service/reassign/step4_controller.js|borderStyle=solid}

if (App.get('isHaEnabled')) {
      var nameServices = configs['hdfs-site']['dfs.nameservices'];
      var suffix = (configs['hdfs-site']['dfs.namenode.http-address.' + nameServices + '.nn1'] === sourceHostName + ':50070') ? '.nn1' : '.nn2';
      configs['hdfs-site']['dfs.namenode.http-address.' + nameServices + suffix] = targetHostName + ':50070';
      ...
    }
{code}
