two name nodes are stand by after configuring HA

[#1]

i have configured high availability in my cluster which consists of three nodes

hadoop-master(192.168.4.128)(name node)

hadoop-slave-1(192.168.4.111) (another name node )

hadoop-slave-2 (192.168.4.106) (data node)

without formatting name node ( converting a non-HA-enabled cluster to be HA-enabled) as described here https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithQJM.ht...

but i got two name nodes working as standby so i tried to move the transition of one of these two nodes to active by applying the following command

 hdfs haadmin -transitionToActive mycluster --forcemanual

with the following out put

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

what should the service address value be ? and what are possible solutions i can apply in order to turn on one name node of the two nodes to active state ?

note the zookeeper server on all three nodes is stopped

[#2]

Please add zkcli command to login in znode and remove directory. Hope you understand.

zookeeper-client -server <zookeeper-server-host>:2181
(May use sudo if permission issue or login from HDFS User)
ls / or ls /hadoop-ha
(If you don't see any znode /hadoop-ha in ZK znode list, skip the step below)
rmr /hadoop-ha/nameservice1
