I use JobListener#onJobExecuted to be notified that the flink job is done. It is pretty reliable for me, the only exception is the client process is down.
BTW, the reason you see ApplicationNotFound exception is that yarn app is terminated which means the flink cluster is shutdown. While for standalone mode, the flink cluster is always up.
