Thille > Assignee: Andor Molnar > Priority: Blocker > Labels: easyfix, patch, pull-request-available > Fix For: 3.6.0, 3.4.13, 3.5.5 > > Attachments: ZOOKEEPER-2184.patch > > Time Spent: 10h > Remaining Estimate: 0h > > 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)
