-------------------------------

             Summary: Make invalid managed memory fraction errors more advisory in MemoryManager
                 Key: FLINK-20282
                 URL: https://issues.apache.org/jira/browse/FLINK-20282
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.12.0
            Reporter: Zhu Zhu
             Fix For: 1.12.0


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.
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"
