Jiang Yan Xu created MESOS-496:
----------------------------------
Summary: Refactor the MasterDetector (with 'bool contend' option)
into new MasterDetector and MasterContender.
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
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.
