  I am stuck here for days and ran around network configuration files  any 
  suggestions    could be greatly appreciated thanks a lot  

I just need to make sure Cloudera-manager agent is running on each node and then deploy the cluster or register the node.

There were some errors in the network configuration files ,which I have modified .and also

I could rectify this problem by making sure that the cloud era-manager agent is running on the node.

Thanks

I would follow up on this part of the error: "cannot open `/var/log/cloudera-scm-agent//cloudera-scm-agent.out' for reading: No such file or directory"

Ensure that the directory exists, and that permissions are correct. The failure centers on the lack of that file.

Also check your configuration file (found in /etc/cloudera-scm-agent/config.ini ). log_file=/var/log/cloudera-scm-agent/cloudera-scm-agent.log is the default location.

There are other gotchas like clock skew (i.e. different times on the different boxes) or have mismatched versions/rpms installed, but in this case your first stop is to see why nothing is being written to /var/log/cloudera-scm-agent/cloudera-scm-agent.log
