--------------------------------------
Thank you for your advice [~jark].
For the first option. Do you mean validating the map key type when creating
mapConverter? By this way, I think we still can not deal with the null key
which may produce when job runs. And this forces users to define not null key
type in map.
For the second, I think It is reasonable to ignore entires with null key, for
if not do that, the whole message will be lost.
BTW, how to deal with Multiset type with null key?
Multiset use mapData as output conversion. I think It is reasonable to contain
null key. I am confused that why we deserializate or serializate a `MapNode` as
Multiset not a `ArrayNode`?
