> Going into safemode involves stopping the secret manager's thread. An
> interrupt is sent to this thread. If this occurs while the thread is logging
> an edit, the resulting exception in the thread will cause the NN to exit.
> The fix is to back-port a subset of HDFS-2579 which went into branch 2 &
> trunk.
