> The invalid managed memory fraction errors[1] reported from MemoryManager are not advisory for users to solve the problem. This error happens when managed memory is required for a use case but its weight is 0. See FLINK-20116.
> I think it would be better to enrich the error message to guide users to properly configure "taskmanager.memory.managed.consumer-weights".
> [1] "Caused by: java.lang.IllegalArgumentException: The fraction of memory to allocate must within (0, 1], was: 0.0"
