Jason Gustafson reassigned KAFKA-8653: -------------------------------------- Assignee: Jason Gustafson > Regression in JoinGroup v0 rebalance timeout handling > ----------------------------------------------------- > > Key: KAFKA-8653 > URL: https://issues.apache.org/jira/browse/KAFKA-8653 > Project: Kafka > Issue Type: Bug > Affects Versions: 2.3.0 > Reporter: Jason Gustafson > Assignee: Jason Gustafson > Priority: Blocker > > The rebalance timeout was added to the JoinGroup protocol in version 1. Prior > to 2.3, we handled version 0 JoinGroup requests by setting the rebalance > timeout to be equal to the session timeout. We lost this logic when we > converted the API to use the generated schema definition which uses the > default value of -1. The impact of this is that the group rebalance timeout > becomes 0, so rebalances finish immediately after we enter the > PrepareRebalance state and kick out all old members. This causes consumer > groups to enter an endless rebalance loop. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
