Hi,

I am trying to setup cluster but getting below error:

error: No socket could be created on ('nn1.amazonaws.com', 9000) -- [Errno
99] Cannot assign requested address

I checked nothing is running on port 9000 .
/etc/hosts file contains

127.0.0.1   localhost.amazonaws localhost
::1         localhost.amazonaws localhost
127.0.0.1   localhost.localdomain localhost
127.0.0.1   localdomain localhost
52.xx.xx.1 nn1.amazonaws.com nn1
52.xx.xx.2  nn2.amazonaws.com nn2
52.xx.xx.3 dn1.amazonaws.com dn1
52.xx.xx.4 dn2.amazonaws.com dn2
52.xx.xx.5  dn3.amazonaws.com dn3


The below script also giving the correct result i.e. correct hostname and
ip address.
python -c 'import socket; print socket.getfqdn (), socket.gethostbyname
(socket.getfqdn ())'


Not sure what else to look for.

Please guide.

Thanks

Krish
