Hadoop 2.6.0 Multi Node Installation and Test Run in Ubuntu 14.04
1. You can follow https://gist.github.com/piyasde/17d4f7bc97c0f0820d40 for single node setup for all the machines in cluster
2. Make a user group for Hadoop Users
3. Make same user for hadoop in all the machines where the hadoop setup will be done
4. Select a machine which will be master node.
On that machine vi /etc/hosts and add the ip a name as master not localhost.
vi /etc/hosts
#127.0.0.1 localhost
#127.0.1.1 ubupc1
