          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.

              In a magical world where ponies run free under rainbows, adding restart() as a method to HDFS-326 would be another way to tackle this sort of problem.
