[jira] [Created] (KAFKA-9275) Print assignment and IP address in
the log message when consumer leaves/removed from the group
Badai Aqrandista created KAFKA-9275:
---------------------------------------
Summary: Print assignment and IP address in the log message when consumer leaves/removed from the group
Key: KAFKA-9275
URL: https://issues.apache.org/jira/browse/KAFKA-9275
Project: Kafka
Issue Type: Improvement
Reporter: Badai Aqrandista
In order to simplify identification of which member is causing rebalance, can we add the IP address and the list of topic-partitions assigned to the member that leaves/removed from the group?
And especially in the "reason" string for rebalance:
https://github.com/apache/kafka/blob/2.4/core/src/main/scala/kafka/coordinator/group/GroupCoordinator.scala#L964
https://github.com/apache/kafka/blob/2.4/core/src/main/scala/kafka/coordinator/group/GroupCoordinator.scala#L972
https://github.com/apache/kafka/blob/2.4/core/src/main/scala/kafka/coordinator/group/GroupCoordinator.scala#L1144
https://github.com/apache/kafka/blob/2.4/core/src/main/scala/kafka/coordinator/group/GroupCoordinator.scala#L493
This will allow a much faster investigation when a consumer group is stuck in rebalancing state.
