Description

FSImage.java

    Exception le = null;
    FSImageFile imageFile = null;
    for (int i = 0; i < imageFiles.size(); i++) {
      try {
        imageFile = imageFiles.get(i);
        loadFSImageFile(target, recovery, imageFile, startOpt);
        break;
      } catch (IllegalReservedPathException ie) {
        throw new IOException("Failed to load image from " + imageFile,
            ie);
      } catch (Exception e) {
        le = e;
        LOG.error("Failed to load image from " + imageFile, e);
        target.clear();
        imageFile = null;
      }
    }

Exception le is not used. It can be removed.
