>          Components: namenode, security
>    Affects Versions: 0.23.0
>            Reporter: Daryn Sharp
>            Assignee: Daryn Sharp
>            Priority: Critical
>             Fix For: 0.23.8

> 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.
