Summary: Additional Issues with contender related change
Key: MESOS-892
URL: https://issues.apache.org/jira/browse/MESOS-892
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
Assignee: Yan Xu
Fix For: 0.16.0
There are a few issues with the contender code in master, mostly with regard to
semantic consistency of the APIs.
1. When the detectors (ZooKeeperMasterDetector, LeaderDetector) fail,
subsequent detect() calls should get a Failure directly.
2. ZooKeeperMasterContenderProcess::master should be an option to codify the
fact that it can be unset after construction.
3. ZooKeeperMasterContenderProcess::contend should check if the future for the
previous contend() is still pending and if so it should directly return that
future without recontending.
4. LeaderContender::withdraw() should alway return ‘false’ if there is no
membership to withdraw.
5. GroupProcess::abort() should set all owned memberships as cancelled.
