ASF GitHub Bot commented on ZOOKEEPER-2184: ------------------------------------------- Github user anmolnar commented on the issue: https://github.com/apache/zookeeper/pull/451 @jeffwidman > Should this PR be targeting branch-3.4 or target trunk and then backport to the 3.4 series? The original PR targets 3.4 which is explained in a comment from @fpj on the jira: https://issues.apache.org/jira/browse/ZOOKEEPER-2184?focusedCommentId=15823099&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15823099 > For the 3.5 branch, we will need a different patch because of the reconfiguration changes to StaticHostProvider. I'll work on it once the 3.4 patch gets a +1. > Zookeeper Client should re-resolve hosts when connection attempts fail > ---------------------------------------------------------------------- > > Key: ZOOKEEPER-2184 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2184 > Project: ZooKeeper > Issue Type: Bug > Components: java client > Affects Versions: 3.4.6, 3.4.7, 3.4.8, 3.4.9, 3.4.10, 3.5.0, 3.5.1, 3.5.2, > 3.5.3, 3.4.11 > Environment: Ubuntu 14.04 host, Docker containers for Zookeeper & > Kafka > Reporter: Robert P. Thille > Assignee: Flavio Junqueira > Priority: Blocker > Labels: easyfix, patch > Fix For: 3.5.4, 3.4.12 > > Attachments: ZOOKEEPER-2184.patch > > > Testing in a Docker environment with a single Kafka instance using a single > Zookeeper instance. Restarting the Zookeeper container will cause it to > receive a new IP address. Kafka will never be able to reconnect to Zookeeper > and will hang indefinitely. Updating DNS or /etc/hosts with the new IP > address will not help the client to reconnect as the > zookeeper/client/StaticHostProvider resolves the connection string hosts at > creation time and never re-resolves. > A solution would be for the client to notice that connection attempts fail > and attempt to re-resolve the hostnames in the connectString. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
