Hadoop Upgrade Wiki

[Mayuran Yogarajah]

Step 8 of the upgrade process mentions copying the 'edits' and 'fsimage' 
file

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I'm not sure if the Wiki is outdated or not.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

Anyone can create themselves an account on the wiki and modify any page.
