Description

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
