Till Rohrmann created FLINK-18677: ------------------------------------- Summary: ZooKeeperLeaderRetrievalService does not invalidate leader in case of SUSPENDED connection Key: FLINK-18677 URL: https://issues.apache.org/jira/browse/FLINK-18677 Project: Flink Issue Type: Bug Components: Runtime / Coordination Affects Versions: 1.11.1, 1.10.1, 1.12.0 Reporter: Till Rohrmann Fix For: 1.12.0
The {{ZooKeeperLeaderRetrievalService}} does not invalidate the leader if the ZooKeeper connection gets SUSPENDED. This means that a {{TaskManager}} won't cancel its running tasks even though it might miss a leader change. I think we should at least make it configurable whether in such a situation the leader listener should be informed about the lost leadership. Otherwise, we might run into the situation where an old and a newly recovered instance of a {{Task}} can run at the same time. -- This message was sent by Atlassian Jira (v8.3.4#803005)
