Till Rohrmann commented on FLINK-11377:
---------------------------------------
Hi [~shengjk1], {{-yn}} will no longer be respected by Flink's new mode. Only
the legacy mode respected this option. The reason is that Flink now dynamically
allocates as many containers as it requires to execute the job. Does this make
sense? If yes, then please close this issue.
