> On UNIX, it would be nice to know when a Hadoop daemon had exited on a signal.  For example,
if a daemon exited because the system administrator sent SIGTERM (i.e. {{killall java}}),
it would be nice to know that.  Although some of this can be deduced from context and {{SHUTDOWN_MSG}},
it would be nice to have it be explicit.
