Cloudera Manager Installation Path A fails with HeartBeat failure Slave Nodes (Virtual Box/CentOS7)

[ Edited ]

Hello All, 

 

I am trying to setup a 4 Node Cluster on CentOS7 in a Virtual Box using CDH Installation Path A. (Using automated way with Parcels)

 

I was able to download the required Parcels and Cloudera-scm-server and Cloudera-scm-agent are running successfully on the respective Master Nodes and datanodes. But After the download 100% completes, it was unable to distribute it to any of the hosts. 

 

I do see that /var/log/cloudera-scm-server/cloudera-scm-server.log has messages with the Heart beat failure.

 

java.net.ConnectException: No route to host to http://datanode2.example.com:9000/heartbeat
java.net.ConnectException: No route to host to http://datanode3.example.com:9000/heartbeat
java.net.ConnectException: No route to host to http://datanode2.example.com:9000/heartbeat
java.net.ConnectException: connection timed out to http://datanode1.example.com:9000/heartbeat
java.net.ConnectException: connection timed out to http://datanode3.example.com:9000/heartbeat
java.net.ConnectException: No route to host to http://datanode2.example.com:9000/heartbeat
java.net.ConnectException: connection timed out to http://datanode1.example.com:9000/heartbeat
java.net.ConnectException: connection timed out to http://datanode3.example.com:9000/heartbeat

 

My /etc/hosts 

 

[root@namenode1 cloudera-scm-server]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.200 namenode1.example.com namenode1
192.168.2.201 datanode1.example.com datanode1
192.168.2.202 datanode2.example.com datanode2
192.168.2.203 datanode3.example.com datanode3
[root@namenode1 cloudera-scm-server]#

 

Note: I have disabled firewalld service on all the hosts. 

 

Am I missing something?. I have tried enough install and uninstall so waiting for any of the valuable inputs.

I have uninstalled the Cloudera Manager and also removed open JDK by using
yum remove java*
Started with Master Node and added two new Hosts later and installation successfully completed.
