> Cached InetSocketAddresses prevent proper dynamic DNS resolution

> Key: ZOOKEEPER-1846
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1846
> Project: ZooKeeper
> Issue Type: Bug
> Components: quorum
> Affects Versions: 3.4.6
> Reporter: Benjamin Jaton
> Priority: Minor
> Labels: patch
> Attachments: DynamicIP.java.patch, Learner.java,
> QuorumCnxManager.java, QuorumPeer.java
>
>
> The class QuorumPeer maintains a Map<Long, QuorumServer> quorumPeers.
> Each QuorumServer is created with an instance of InetSocketAddress
> electionAddr, and holds it forever.
> I believe this is why the ZooKeeper servers can't resolve each other
> dynamically: If a ZooKeeper in the ensemble cannot be resolved at startup, it
> will never be resolved (until restart of the JVM), constantly failing with an
> UnknownHostException, even when the node is back up and reachable.
> I would suggest to recreate an InetSocketAddress every time we retry the
> connection.
