I have successfully set up a cloudera manager with 2 hosts.
But after restarting the vm's containing the hosts the cloudera manager no longer displays any cluster, i can see the 2 hosts in the "Hosts" tab but they are unhealthy. This is a snippet from the health instactor: https://imgur.com/a/2QIdyF5
I have seen a lot of people on google saying to check if the python command for ip and fqdn responds with the correct output, and it does.
Also hdfs/hadoop version displays "Hadoop 3.0.0-cdh6.0.1"
