Re: Problem with Hadoop and /etc/hosts file

2012-09-21 Thread Ravi Mutyala
If you are using VMs and /etc/hosts (not DNS), then it is a good idea to disable DHCP and enable a static IP on the VMs. Follow all the other steps in Harsh's document and it should work. Remember that /etc/hosts should have the actual ip/hostname mapping, not 127.0.0.1 -> hostname mapping.
