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.
