> If DFSOutputStream fails to create a pipeline, it currently sleeps 6 seconds
> before retrying. I don't see a great reason to wait at all, much less 6
> seconds (especially now that HDFS-630 ensures that a retry won't go back to
> the bad node). We should at least make it configurable, and perhaps something
> like backoff makes some sense.
