-------------------------------------
Summary: Decouple leader address from LeaderContender
Key: FLINK-14287
URL: https://issues.apache.org/jira/browse/FLINK-14287
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.10.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.10.0
At the moment, the {{LeaderContender}} need to know the address of the leader
before it has gained leadership. This is problematic if one wants to decouple
the leader election from the actual leader component which will potentially
only be created after the leadership has been gained. If this is the case, then
it is not always possible to know the address of the actual leader component
before gaining the leadership.
In order to solve this problem, I propose to change the interface of
{{LeaderElectionService#confirmLeadership(UUID)}} to
{{LeaderElectionService#confirmLeadership(UUID, String)}} where the second
parameter is the leader address under which the leader component is reachable.
