While YARN-373 addresses a bit of a different problem the use case of reuse of existing resources could be looked at few different ways. As I understand YARN-373 talks about reusing resources from an old container to spun off a new one. Another way of looking at the problem is to actually reuse a container itself as long as you can communicate with it. I've been experimenting with it recently and while I am not sure if the approach is valid or solves your use case, take a look here https://github.com/olegz/yaya/wiki/CoreFeatures#java-based-long-running-and-interact-able-application-containers. At least you'll get some ideas of what could be done.
