Description

The following piece of code has been in the FrameworkUploader class for a while:

  private void validateTargetPath() throws UploaderException {
    if (!target.startsWith("hdfs:/") &&
        !target.startsWith("file:/")) {
      throw new UploaderException("Target path is not hdfs or local " + target);
    }
  }

As parts of MR and YARN has evolved, you can run YARN with OzoneFS as storage for instance - so HDFS (or local) is not a requirement anymore. Also it does not make sense to add other suitable filesystems when they're tested against the MR framework, so I'm suggesting to remove the check.
