This is fantastic Bgooley! Your solution worked.  The cloned VM indeed had the same UUID as the parent. As per your instructions, we stopped the scm agent, deleted the uuid and restarted scm agent. We then added the node to the cluster via Cloudera Manager and it got registered correctly. We can now see both the VM nodes.   Thank you so much! Appreciate your help. ... View more

Hi,   We have the same problem i.e. when we use 2 clones of the same VM and try to connect the Master node to them, only one of them is visible at a time. We have gone through the thread above and made sure that -  i) Hostnames of the 2 VMs are different ii) Hostids of the 2 VMs are different iii) /etc/hosts has names and IPs of all 3 machines i.e. Master, Node1 and Node2 iv) Physical addresses of the 2 VMs is different   However, the problem persists. Any further inputs into what could be causing the issue please? Any help would be appreciated.   Thanks in advance.   Regards, Yogesh ... View more

Thanks Michalis. I realise that once the ssh password is changed on the SSH screen (as shown in your response), it will be picked up seamlessly.   However, if I change the 'cloudera' user's password via the Linux command line, will it impact any of the Hadoop services e.g. after the password change, will services like HDFS/MR/Hbase/Hive/Zookeeper stop working because they were originally configured to run using a different password? ...
