    Description

      With the addition of AvatarNode, we are working on a rolling restart option for upgrading a cluster. It seems that a generic restart option would be useful for this purpose and perhaps other administrative tasks. Add a 'restart' option to hadoop-daemon.sh and also modify 'slaves.sh' to run operations in parallel or serially.
