Description

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.
