There is no specific procedure for configuring virtual machine slaves.
make sure the following thing are done.
1.All machine's(both VM's and physical machines) public key are distributed
to all "~/.ssh/authorized_keys" file.
2.conf/hadoop-site.xml file is similar for all the machines.
3.etc/hosts file must contain all the machines(VM,Physical machine) IP and
Hostname.
4.conf/slaves must contain hostname of all slaves including VM's and
physical machine.
5.conf/masters must contain only master's hostname.
6.both conf/masters and conf/slaves files must be similar in all the
participating machines.
7.hadoop home directory should be same for all the machines like
"/root/hadoop-0.18.2/"
8.finally execute the Namenode -format command only in the Master machine.
