Frederic Tardif commented on KAFKA-7849: ---------------------------------------- got the same issue: {code:java} [2019-05-08 09:54:24.212] WARN [uepg-catalog_program-snapshot-connector-7ddde56e-7dff-4a14-aa11-6c8fb22b40ce-StreamThread-2] [Consumer clientId=uepg-catalog_program-snapshot-connector-7ddde56e-7dff-4a14-aa11-6c8fb22b40ce-StreamThread-2-consumer, groupId=uepg-catalog_program-snapshot-connector] The following subscribed topics are not assigned to any members: [livecms.program.snapshot] - (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator:?) {code} My topology is a globalTable: {code:java} streamBuilder.globalTable(config.getTopicName(), Materialized.as(config.getStoreName()));{code} {quote}I confirm my consumer lag in the rocksdb checkpoint file did indeed show the expected partition offset. In addition the warning disappeared the third time I had restarted it (maybe however caused by the store already in sync). I would be surprised in that case that fiddling with the number of stream thread configuration is required. So it looks like a self healed kind of warning. The message however does not sound that reassuring... Next time I'll get this I'll try enabling debug logs to correlate the warning. {quote} > Warning when adding GlobalKTable > -------------------------------- > > Key: KAFKA-7849 > URL: https://issues.apache.org/jira/browse/KAFKA-7849 > Project: Kafka > Issue Type: Bug > Components: streams > Affects Versions: 2.1.0 > Reporter: Dmitry Minkovsky > Priority: Minor > Labels: newbie > > Per > https://lists.apache.org/thread.html/59c119be8a2723c501e0653fa3ed571e8c09be40d5b5170c151528b5@%3Cusers.kafka.apache.org%3E > > When I add a GlobalKTable for topic "message-write-service-user-ids-by-email" > to my topology, I get this warning: > > [2019-01-19 12:18:14,008] WARN > (org.apache.kafka.clients.consumer.internals.ConsumerCoordinator:421) > [Consumer > clientId=message-write-service-55f2ca4d-0efc-4344-90d3-955f9f5a65fd-StreamThread-2-consumer, > groupId=message-write-service] The following subscribed topics are not > assigned to any members: [message-write-service-user-ids-by-email] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
