Todd Lipcon commented on HDFS-1566:
-----------------------------------
I'm not sure - iirc the behavior we had when we saw this bug was really strange
- when we hit the end of the disk, the NN exit(1)ed rather than seeing nice
exceptions. So fault injection may not be able to reproduce quite the same nasty

> We've seen the following bug, hdfs needs a test to reproduce this:
> * /var filled up
> * 2NN failed checkpoint due to no space left on device
> * NN log hit end of disk
> * NN seems to have exited on the spot, mid-log-message
> * NN edits are left corrupted
> ** Half of a rename made it into the log
> ** valid data appears to end on a sector boundary
> ** this is true across all of the edit dirs
