-------------------------------------
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.
