Highly Available AMQP via Spring Integration and RabbitMQ - Issue - rabbitmq

Question

WHAT I DID:
I am using RabbitMQ message broker which supports the AMQP standard in my spring micro services. Its main purpose is to prevent the message losing, during the rabbitMQ server (unfortunate) shutdown. So I am planning to give the Highly Available AMQP Backed Message Channels.
I tried to setup two RabbitMQ servers and I followed the below link to setup the RabbitMQ servers.

First RabbitMQ Server’ s config file(rabbitmq.config) is as follows. It should be put under ../rabbitmq_server-version/etc/rabbitmq/
[
{rabbit, [ {tcp_listeners, [5672]},
{collect_statistics_interval, 10000},
{heartbeat,30},
{cluster_partition_handling, pause_minority},
{cluster_nodes, {[ 'rabbit#master',
'rabbit2#master'],
disc}} ] },
{rabbitmq_management, [ {http_log_dir,"/tmp/rabbit-mgmt"},{listener, [{port, 15672}]} ] },
{rabbitmq_management_agent, [ {force_fine_statistics, true} ] }
].
Second RabbitMQ Server’ s rabbitmq.config file :
[
{rabbit, [ {tcp_listeners, [5673]},
{collect_statistics_interval, 10000},
{heartbeat,30},
{cluster_partition_handling, pause_minority},
{cluster_nodes, {[ 'rabbit#master',
'rabbit2#master'],
disc}} ] },
{rabbitmq_management, [ {http_log_dir,"/tmp/rabbit-mgmt"},{listener, [{port, 15673}]} ] },
{rabbitmq_management_agent, [ {force_fine_statistics, true} ] }
].
First RabbitMQ Server’ s sample bash script is as follows. Also please have a look RabbitMQ Cluster documentation for other configuration steps.
#!/bin/bash
echo "*** First RabbitMQ Server is setting up ***"
export RABBITMQ_HOSTNAME=rabbit#master
export RABBITMQ_NODE_PORT=5672
export RABBITMQ_NODENAME=rabbit#master
export RABBITMQ_SERVER_START_ARGS="-rabbitmq_management listener [{port,15672}]"
/DEV_TOOLS/rabbitmq_server-3.4.2/sbin/rabbitmq-server &
echo "*** Second RabbitMQ Server is set up succesfully. ***"
sleep 5
echo "*** First RabbitMQ Server' s status : ***"
/DEV_TOOLS/rabbitmq_server-3.4.2/sbin/rabbitmqctl status
Second RabbitMQ Server’ s sample bash script is as follows :
#!/bin/bash
echo "*** Second RabbitMQ Server is setting up ***"
export RABBITMQ_HOSTNAME=rabbit2#master
export RABBITMQ_NODE_PORT=5673
export RABBITMQ_NODENAME=rabbit2#master
export RABBITMQ_SERVER_START_ARGS="-rabbitmq_management listener [{port,15673}]"
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmq-server &
echo "*** Second RabbitMQ Server is set up succesfully. ***"
sleep 5
echo "*** Second RabbitMQ Server' s status : ***"
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmqctl status
sleep 5
echo "*** Second RabbitMQ Server is being added to cluster... ***"
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmqctl -n rabbit2#master stop_app
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmqctl -n rabbit2#master join_cluster rabbit#master
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmqctl -n rabbit2#master start_app
/DEV_TOOLS/rabbitmq_server-3.4.2/sbin/rabbitmqctl -n rabbit#master set_policy ha-all "^ha\." '{"ha-mode":"all"}'
echo "*** Second RabbitMQ Server is added to cluster successfully... ***"
sleep 5
echo "*** Second RabbitMQ Server' s cluster status : ***"
/DEV_TOOLS/rabbitmq_server-3.4.2_2/sbin/rabbitmqctl cluster_status
WHAT IS ISSUE:
I can see that two RabbitMQ servers are running synchronously.
When I stop the first node, the second node is working.
sbin/rabbitmqctl stop_app
But When I shut down the first RabbitMQ server, the second node also going down.
sbin/rabbitmqctl stop
But, The result should be,
If First Messaging Node and First RabbitMQ Server are shut down
accidentally, Second Messaging Node and Second RabbitMQ Server will
continue to process Order messages so potential message loosing and
service interruption problems can be prevented by using high available
AMQP backed channel.
Kindly help me to fix this issue. Thanks.
