Till Rohrmann commented on FLINK-7076:
--------------------------------------

Hi [~yuemeng], let's first tackle the second problem which is how to release a 
container on the RM side. This basically means how to give it back to Yarn. I 
think the {{YarnResourceManager#stopWorker}} method should do this.

> Implement container release to support dynamic scaling
