to a backup directory. After step 19 it says: 'In case of failure the administrator should have the checkpoint files in order to be able to repeat the procedure from the appropriate point or to restart the old version of Hadoop.'
Is this different from running 'start-dfs.sh -rollback' ?I'm not sure if the Wiki is outdated or not. If its the same then step #8 can be skipped
altogether I'm guessing.. thanks
