    Description

      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.

      % bin/hadoop namenode -finalize
