> Since the MR2 daemons are made up of lots of component services, if one of
> those components fails to start, it will cause the others to shut down as
> well, even if they haven't fully finished starting up. Currently, this causes
> the error output to have a bunch of NullPointerExceptions,
> IllegalStateExceptions, etc, which mask the actual root cause error at the
> top.
