> Running yarn per-job cluster in detached mode currently does not work and 
> waits for the job to finish.
> Example:
> {code}
> ./bin/flink run -m yarn-cluster -yn 10 -yjm 768 -ytm 3072 -ys 2 -yd -p 20 -c 
> org.apache.flink.streaming.examples.wordcount.WordCount 
> ./examples/streaming/WordCount.jar --input
> {code}
> Output in case of an infinite program would then end with something like this:
> {code}
> 2018-03-05 13:41:23,311 INFO  
> org.apache.flink.yarn.AbstractYarnClusterDescriptor           - Waiting for
