我在由三个节点组成的集群中配置了高可用性
hadoop主机（192.168.4.128）（名称节点）
hadoop-slave-1（192.168.4.111）（另一个名称节点）
hadoop-slave-2（192.168.4.106）（数据节点）
不格式化名称节点（将未启用ha的集群转换为启用ha的集群），如下所述https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/hdfshighavailabilitywithqjm.html
但是我有两个name节点作为备用节点工作，所以我尝试通过应用以下命令将这两个节点中的一个转换为active

hdfs haadmin -transitionToActive mycluster --forcemanual

有以下输出

17/04/03 08:07:35 WARN ha.HAAdmin: Proceeding with manual HA state management even though
automatic failover is enabled for NameNode at hadoop-master/192.168.4.128:8020
17/04/03 08:07:36 WARN ha.HAAdmin: Proceeding with manual HA state management even though

服务地址值应该是什么？为了使两个节点中的一个名称节点处于活动状态，我可以应用哪些可能的解决方案？
注意，所有三个节点上的zookeeper服务器都已停止
