> Picking up a thread again from MAPREDUCE-987, I've found it very useful to 
> have a CLI driver for running a single-process DFS cluster, particularly when 
> developing features in HDFS clients. For example, being able to spin up a 
> local cluster easily was tremendously useful for correctness testing of 
> HDFS-2834. 
> I'd like to contribute a class based on the patch for MAPREDUCE-987 we've 
> been using fairly extensively. Only for DFS, not MR since much has changed 
> MR-side since the original patch.
