Description

When you convert a 0.13 NameNode storage directory from pre to post HADOOP-1242, the NameNode won't start. You'll get:

07/06/04 00:10:51 ERROR dfs.NameNode: org.apache.hadoop.dfs.InconsistentFSStateException: Directory /data/hadoop/dfs/name is in an inconsistent state: /data/hadoop/dfs/name/image does not exist.

because the "bad" image file isn't created later in the startup. Since this is only a non-release issue, I don't know if we need to fix it programatically or can just provide an upgrade script. Thoughts?
