Till Rohrmann commented on FLINK-12362:
---------------------------------------
At the moment there is no way to configure a fixed number of containers. Flink
will try to allocate as many containers as there are necessary to run the
submitted job. If you define for every operator a different slot sharing group,
then you would need to know how many operators there are in your job to
calculate the total number of required slots.
> Remove legacy container number config option for Flink on yarn
