> The test deletes the shared edits dir to simulate a failure. Then it calls
> rollEditLogs() to trigger the deleted dir to be used and fail with an
> IOException. Unfortunately, deleting the shared dir can put the NN in safe
> mode due to lack of space. This causes a SafeModeException to be thrown when
> rollEditDirs() is called. This exception is caught as an IOException in the
> test but the associated assert in the catch block fails.
> This always happens in the debugger because the delay in stepping through
> causes the safe mode change to happen before rollEditLogs() gets called.
