Summary: StreamPartitionAssignor doesn't respect subscriptions to asisgn partitions. Key: KAFKA-4905 URL: https://issues.apache.org/jira/browse/KAFKA-4905 Project: Kafka Issue Type: Bug Components: streams Affects Versions: 0.10.2.0 Reporter: Florian Hussonnois Both RangeAssignor and RoundRobinAssignor use the subscriptions to assign partition to each consumer. This allow to have two consumers belonging to the the same group and subscribing to two differents topics. This doesn't seem to be the case of the StreamPartitionAssignor resulting to an IllegalArgumentException thrown during rebalance. java.lang.IllegalArgumentException: Assigned partition foo-2 for non-subscribed topic regex pattern; subscription pattern is bar at org.apache.kafka.clients.consumer.internals.SubscriptionState.assignFromSubscribed(SubscriptionState.java:190) at org.apache.kafka.clients.consumer.internals.ConsumerCoordinator.onJoinComplete(ConsumerCoordinator.java:216) at org.apache.kafka.clients.consumer.internals.AbstractCoordinator.joinGroupIfNeeded(AbstractCoordinator.java:352) at org.apache.kafka.clients.consumer.internals.AbstractCoordinator.ensureActiveGroup(AbstractCoordinator.java:303) This is because the consumer group leader attempt to assign partitions to a consumer that didn't subscribe to the associated topic. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
