----------------------------
Summary: Group::cancel can return a failed future if the
membership is already cancelled
Key: MESOS-811
URL: https://issues.apache.org/jira/browse/MESOS-811
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
Assignee: Yan Xu
Fix For: 0.16.0
The API stipulates that a successful Future<bool> but with 'false' value should
be returned.
This can happen when:
1) The cancel() operation is queued up due to connectivity issue but then
invoked again by sync() the membership could be gone.
2) Even if not delayed, in cancel() we first checked whether the membership
exists in our local cache but the membership could have expired by then (or
when we invoke zk->remove(...)) but we have yet to receive the update for it.
