Can you ping those exact hostnames from the CM server host? - Jeremy Beard
Yes. All the hosts are connected, /etc/hosts files updated. Instead of parcels, I used packages second time and it all worked fine. - Anan

The problem is DNS error, Cloudera manager is not able to resolve the below hostname, you need to set up properly configure DNS servers in all nodes or modify your /etc/hosts file and add hostnames and the corresponding ip-address to that file in the below format. 

127.0.0.1   localhost 
::1         localhost 
<ip-Addr1>  vm-cdh-cluster-1

<ip-Addr1>  vm-cdh-cluster-2
