Benjamin Bannier commented on MESOS-9901:
-----------------------------------------
[~mzhu], could you document the expected behavior? AFAICT we already e.g., test
that output produced by {{JSON::protobuf}} can be parsed back to proto maps,
see {{ProtobufTest.JsonifyMap}} in {{3rdparty/stout/tests/protobuf_tests.cpp}}.
If we do any changes there we should make sure to not break our JSON API.
> Specialize jsonify for protobuf Maps.

> Key: MESOS-9901
> URL: https://issues.apache.org/jira/browse/MESOS-9901
> Project: Mesos
> Issue Type: Improvement
> Components: json api
> Reporter: Meng Zhu
> Priority: Major
>
> Jsonify current treats protobuf as a regular repeated field. For example, for
> the schema
> {noformat}
> message QuotaConfig {
> required string role = 1;
> map<string, Value.Scalar> guarantees = 2;
> map<string, Value.Scalar> limits = 3;
> }
> {noformat}
> it will produce:
> {noformat}
> "configs": [
> {
> "role": "role1",
> "guarantees": [
> {
> "key": "cpus",
> "value": {
> "value": 1
> }
> },
> {
> "key": "mem",
> "value": {
> "value": 512
> }
> }
> ]
> {noformat}
> This output cannot be parsed back to proto messages. We need to specialize
> jsonify for Maps type.
