>             Project: Mesos
>          Issue Type: Improvement
>          Components: json api

> 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.
