Qian Zhang updated MESOS-7656:
------------------------------
Story Points: 3
> Update the JSON <=> protobuf message conversion for map support
> ---------------------------------------------------------------
>
> Key: MESOS-7656
> URL: https://issues.apache.org/jira/browse/MESOS-7656
> Project: Mesos
> Issue Type: Improvement
> Reporter: Qian Zhang
> Assignee: Qian Zhang
>
> [Map|https://developers.google.com/protocol-buffers/docs/proto#maps] is a
> feature starting from proto2 syntax, but it can only be compiled with proto3
> compiler, see the following discussion for details:
> https://groups.google.com/forum/#\!topic/protobuf/p4WxcplrlA4
> We have already upgraded the protobuf compiler from 2.6.1 to 3.3.0 in
> [MESOS-7228|https://issues.apache.org/jira/browse/MESOS-7228], however, to
> use protobuf map in Mesos code, we also need to add the protobuf map support
> to the code in Mesos for converting protobuf message to JSON object and
> parsing JSON object as protobuf message, that is what we plan to handle in
> this ticket.
> With map support added, the following field in the protobuf message can be
> replaced by the native protobuf map field, and we do not have to manually
> parse it anymore.
