> Add ability to decode JSON serialized MasterInfo from ZK
> --------------------------------------------------------
>
> Key: MESOS-2340
> URL: https://issues.apache.org/jira/browse/MESOS-2340
> Project: Mesos
> Issue Type: Improvement
> Components: leader election
> Reporter: Zameer Manji
> Assignee: Marco Massenzio
> Labels: mesosphere
> Fix For: 0.23.0
>
>
> Currently to discover the master a client needs the ZK node location and
> access to the MasterInfo protobuf so it can deserialize the binary blob in
> the node.
> I think it would be nice to publish JSON (like Twitter's ServerSets) so
> clients are not tied to protobuf to do service discovery.
> This ticket is an intermediate (compatibility) step: we add in {{0.23}} the
> ability for the {{Detector}} to "understand" JSON **alongside** Protobuf
> serialized format; this makes it compatible with both earlier versions, as
> well a future one (most likely, {{0.24}}) that will write the {{MasterInfo}}
> information in JSON format.
