Master node etc-hosts file being cleared

["Susumu Urata \(Technocross\)" <susumu_urata@xxxxxxxxxxxxxxx>]

Master node /etc/hosts file being wiped out with the gluster HPC 
node information.  It should be just added rather than creating a 
new hosts file so that the customer can maintain the access to the 
world.  Keeping a back-up file is one way but the new node addresses 
are rather be added.

If there are other files being removed, they should be also just 
modified.
