Subject Name Node Corruption When Shutdown Too Soon
Date Sun, 07 Feb 2010 16:45:10 GMT
I've come across a name node bug and just wanted to check if it's a known issue before I formally
raise it (I've had a quick look through the database but couldn't see anything obvious).

If the name node is shut down before it has completed reading through the edit log then the
edit log gets removed without the image file being updated.  This results in name node reverting
to its previously saved state (out of sync with the data nodes) and the most recent edits
getting lost.

Does anybody recognise this as a known issue or should I raise it?
