Examples of saveDigestAndRenameCheckpointImage()

org.apache.hadoop.hdfs.server.namenode.FSImage.saveDigestAndRenameCheckpointImage()
This is called by the 2NN after having downloaded an image, and by the NN after having received a new image from the 2NN. It renames the image from fsimage_N.ckpt to fsimage_N and also saves the related .md5 file into place.
