> REEF supports heartbeating regarding its own health towards the YARN and Mesos master
and the client that spawned the REEF job. What is missing is the reverse: Sometimes, REEF
applications need to implement fate sharing with the program / service that launched them.
If that service dies, we want the REEF application to shutdown as well.
