Description

One of the really useful artifacts in bigtop is the init-hdfs.sh script. It defines ecosystem semantics and expectations for hadoop clusters.

Other HCFS filesystems can leverage the logic in this script quite easily, if we decouple its implementation from being HDFS specific by specifying a "SUPERUSER" parameter to replace "hdfs".

And yes we can still have the init-hdfs.sh convenience script : which just calls "init-hcfs.sh hdfs" .

Initial tests in puppet VMs pass. (attaching patch with this JIRA)
