Till Rohrmann created FLINK-6342: ------------------------------------ Summary: Start ZooKeeperLeaderElectionService under lock to avoid race condition Key: FLINK-6342 URL: https://issues.apache.org/jira/browse/FLINK-6342 Project: Flink Issue Type: Bug Components: Distributed Coordination Affects Versions: 1.3.0 Reporter: Till Rohrmann Assignee: Till Rohrmann Fix For: 1.3.0
The {{ZooKeeperLeaderElectionService}} should start its components under the {{lock}} in order to avoid race conditions with the {{LeaderLatchListener's}} callback {{isLeader}}. If this is not done, then a leader notification might go unnoticed from the election service because the {{LeaderLatch}} has been started but the internal state of the election service has not been set to running yet. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
