[jira] [Created] (ZOOKEEPER-5063) ZooKeeper observer master needs to dynamically resolve socket addresses

Li Wang created ZOOKEEPER-5063:
----------------------------------

             Summary: ZooKeeper observer master needs to dynamically resolve socket addresses
                 Key: ZOOKEEPER-5063
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-5063
             Project: ZooKeeper
          Issue Type: Bug
          Components: quorum, server
    Affects Versions: 3.8.6, 3.9.5, 3.7.2, 4.0.0, 3.10.0
         Environment: - Kubernetes deployments where ZooKeeper participants run as pods
- Observer Master feature enabled (`observerMasterPort` configured)
- DNS-based service discovery
            Reporter: Li Wang
            Assignee: Li Wang


Observer Master feature does not dynamically recreate socket addresses when connecting to learner master, causing connection failures in Kubernetes environments where participant pods get rescheduled with new IP addresses.
