Matthias commented on FLINK-12110:
----------------------------------

Is this still a topic considering the resolution of FLINK-14422? There, we 
exposed the newly introduced metrics for the actual shuffle memory usage.

> Introduce API point for ShuffleEnvironment to get estimation of locally 
> required memory

> At the moment, we use static method TaskManagerServices.calculateHeapSizeMB 
> to estimate local memory needed in TM container for network environment. As 
> network environment becomes pluggable shuffle service, we should also make 
> this request from container to shuffle service pluggable.
