Temporary failure in name resolution while run Hadoop/bin/start-all.sh

I caught "Temporary failure in name resolution" while run Hadoop/bin/start-all.sh on my SUSE Linux.I have searched many website to look for the problem,but can not find the effective answer. I look forward your help,thank you!!

It is deployed on single same maching,so in both master/slaves files only one line:localhost

Maybe you can know what happened!

I had the same problem and I've resolved it adding to /etc/hosts file the next line: 192.168.56.101 localhost hadoop where you must change the ip and change hadoop and put your own hostname.
