      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:

      ambari-web/app/controllers/main/service/reassign/step4_controller.js
      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';
            ...
          }
