             Summary: Duplicate MapSerializer and HashMapSerializer.
                 Key: FLINK-8841
                 URL: https://issues.apache.org/jira/browse/FLINK-8841
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing, Type Serialization System
    Affects Versions: 1.5.0
            Reporter: Kostas Kloudas
            Assignee: Kostas Kloudas
             Fix For: 1.5.0

Currently there are two class MapSerializer and HashMapSerializer whose code is 
the same with the only difference being that one includes elements of type Map 
and the other HashMap. 

In addition, these two were merged on the same commit. 

I would like to remove the HashMapSerializer. I already created a branch 
without the HashMapSerialzer and nothing seems to be failing on Travis. The 
reasons why I hesitate to do it, is because I am not sure if this may create 
problems with Backwards Compatibility.

[~xiaogang.sxg] could you elaborate a bit on why they were both added and if 
there is any danger in removing the HashMapSerializer?

Also [~StephanEwen] and [~stefanrichte...@gmail.com] it is worth having a look 
and if you are ok, I can remove the redundant serializer.
