[#1]

Hi All,

I am getting this error when install Cloudera Manager - 

CDH 5.2.1-1.cdh5.2.1.p0.12 1 Error(s)

• Error when distributing to hslave : [Errno socket error] [Errno -2] Name or service not known.

hslave is 1 of my slave machine.

This is a classic error where name services are not configured correctly.
Please include each node in the /etc/hosts of each node. The contents
should be similar to

10.10.10.10 hostname.domain.com hostname

If you are using DNS, ensure each node's hostname can be resolved from
every other node

I have set both the servers names in the hosts file on both the machine, but still giving error.

Can you paste the contents of your /etc/hosts file? Also run this
command on your CM host as well as hslave and paste the results here.

# python -c "import socket; print socket.getfqdn(); print
socket.gethostbyname(socket.getfqdn())"
