Henry Robinson updated HDFS-3167:
---------------------------------
Attachment: HDFS-3167.1.patch
Removed unused 'stop', and unused default for nn port, also moved all
System.*.println to LOG.
Regarding testing: informally I've been using it internally for a couple of
months, and I've worked through the command line options to verify that they
behave as expected before creating this patch.

> 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.
