Till Rohrmann commented on FLINK-15058:
---------------------------------------
All serious users will have configured the task executor memory anyways. Hence,
it should only affect toy use cases. Moreover, we are outputting a descriptive
error message so that the user knows what to do. Consequently, I believe that
this should not be a big problem.
