> Key: MESOS-496
> URL: https://issues.apache.org/jira/browse/MESOS-496
> Project: Mesos
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.14.0
> Reporter: Jiang Yan Xu
> Assignee: Jiang Yan Xu
>
> The MasterDetector code still uses old Zookeeper abstractions and it's
> error-prone for maintenance and further development.
> There exists newer and higher-level zookeeper group management abstractions
> such as zookeeper::Group. After this refactoring Mesos master detecting and
> contending logic should reside in separate classes which depend on general
> Zookeeper group leader detection and contention abstractions with
> Future-pattern APIs. Masters should then use the MasterContender while Slaves
> and Schedulers should use the MasterDetector.
