I am facing a DNS resolution problem with 2 of my hosts in my cluster.
/etc/hosts file is configured like : ip FQDN hostname for all hosts
python -c "import socket; print socket.getfqdn(); print socket.gethostbyname(socket.getfqdn())"
gives me back the correct values ,
also i can ping each host with hostname normally
But still i cannot avoid this issue about DNS resolution .
Also the hosts IDs are different .
Any ideas pls ?
