Konstantin Shvachko updated HADOOP-1604:
----------------------------------------
Issue Type: New Feature (was: Bug)
I agree it would be useful to have -finalize option for the name-node startup.
This is a new feature. Not a bug. Do we have feature freeze in progress for
0.14 already?
> admins should be able to finalize namenode upgrades without running the
> cluster

> URL: https://issues.apache.org/jira/browse/HADOOP-1604
> Project: Hadoop
> Issue Type: New Feature
> Components: dfs
> Affects Versions: 0.14.0
> Reporter: Owen O'Malley
> Assignee: Konstantin Shvachko
> Priority: Blocker
> Fix For: 0.14.0
>
>
> Currently a HDFS cluster must be running in order to finalize an upgrade, but
> if you shut down without finalizing the new software won't start up. I
> propose a command line option to the namenode that lets you finalize an
> upgrade with the cluster down.
> {code}
> % bin/hadoop namenode -finalize
