Thille > Assignee: Andor Molnar > Priority: Blocker > Labels: easyfix, patch, pull-request-available > Fix For: 3.4.13 > > Attachments: ZOOKEEPER-2184.patch > > Time Spent: 9h 10m > 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)
