             Summary: Align the behavior of result of internal map state to 
return empty iterator
                 Key: FLINK-17610
                 URL: https://issues.apache.org/jira/browse/FLINK-17610
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / State Backends
    Affects Versions: 1.11.0
            Reporter: Nicholas Jiang


There are different behaviors of result of internal map state. For 
HeapMapState, #entries(), #keys(), #values(), and #iterator() would all return 
null. However, for RocksDBMapState, #entries() would return null, while 
#keys(), #values(), #iterator() would return empty iterator. UserFacingMapState 
would align these behaviors to empty iterator for users, therefore this should 
better align these internal behavior to return empty iterator instead of null.
