> For example, you can't use -D options on the "hadoop fs" command line in
> order to specify the deprecated names of configuration options. The issue is
> that the ordering is:
> - JVM starts
> - GenericOptionsParser creates a Configuration object and calls set() for
> each of the options specified on command line
> - DistributedFileSystem or other class eventually instantiates
> HdfsConfiguration which adds the deprecations
> - Some class calls conf.get("new key") and sees the default instead of the
> version set on the command line
