Joe,
It looks like you edits file is corrupted or truncated.
Most probably the last modification was not written to it,
when the name-node was turned off. This may happen if the
node crashes depending on the underlying local file system I guess.
Here are some options for you to consider:
- try an alternative replica of the image directory if you had one.
- try to edit the edits file if you know the internal format.
- try to modify local copy of your name-node code, which should
catch EOFException and ignore it.
- Use a checkpointed image if you can afford to loose latest modifications to
the fs.
- Formatting of cause is the last resort since you loose everything.
Thanks,

and how to prevent this. Has anyone seen this and can advise?
Thanks in advance,
