Hi all, I am having trouble getting details on a consumer group I am using. I would appreciate the help! Here is what I'm doing.
*1. Launch a Kafka 0.9.0.1 and Consumer with group.id <http://group.id>=testGroup* *2. I start receiving messages just fine. * *3. I can see my group in the 0.9.0.1 Broker logs: * [2016-04-14 16:26:28,757] INFO [GroupCoordinator 2]: Assignment received from leader for group testGroup for generation 1 (kafka.coordinator.GroupCoordinator) [2016-04-14 16:27:15,362] INFO [Group Metadata Manager on Broker 2]: Removed 0 expired offsets in 0 milliseconds. (kafka.coordinator.GroupMetadataManager) [2016-04-14 16:32:59,467] INFO [GroupCoordinator 2]: Preparing to restabilize group testGroup with old generation 1 (kafka.coordinator.GroupCoordinator) [2016-04-14 16:33:01,783] INFO [GroupCoordinator 2]: Stabilized group testGroup generation 2 (kafka.coordinator.GroupCoordinator) *4. I can see my group in the Consumer logs: * 14 Apr 2016 16:26:28.760 [32345] DEBUG #splapptrc,J[14],P[119],KafkaStreamTest M[AbstractCoordinator.java:org.apache.kafka.clients.consumer.internals.AbstractCoordinator$SyncGroupRequestHandler.handle:423] - Received successful sync group response for group testGroup: {error_code=0,member_assignment=java.nio.HeapByteBuffer[pos=0 lim=50 cap=50]} 14 Apr 2016 16:26:28.762 [32345] DEBUG #splapptrc,J[14],P[119],KafkaStreamTest *5. BUT...when I try to examine the group, I do: * $ ./kafka-consumer-groups.sh --zookeeper myZkHost:2181 --describe --group testGroup No topic available for consumer group provided GROUP, TOPIC, PARTITION, CURRENT OFFSET, LOG END OFFSET, LAG, OWNER $ ./kafka-consumer-groups.sh --zookeeper myZkHost:2181 --list 1451409432.77249 mygroup 1451409552.27855 My group is nowhere to be found! Thanks for any help or ideas! Alex Here are my Consumer configs: 14 Apr 2016 16:26:28.360 [32152] INFO #splapptrc,J[14],P[119],KafkaStreamTest M[AbstractConfig.java:org.apache.kafka.common.config.AbstractConfig.logAll:165] - ConsumerConfig values: metric.reporters = [] metadata.max.age.ms = 300000 value.deserializer = class org.apache.kafka.common.serialization.StringDeserializer group.id = testGroup partition.assignment.strategy = [org.apache.kafka.clients.consumer.RangeAssignor] reconnect.backoff.ms = 50 sasl.kerberos.ticket.renew.window.factor = 0.8 max.partition.fetch.bytes = 1048576 bootstrap.servers = [g0601b02.some.host.com:9092, g0601b03.some.host.com:9092, g0601b04.some.host.com:9092] retry.backoff.ms = 100 sasl.kerberos.kinit.cmd = /usr/bin/kinit sasl.kerberos.service.name = null sasl.kerberos.ticket.renew.jitter = 0.05 ssl.keystore.type = JKS ssl.trustmanager.algorithm = PKIX enable.auto.commit = true ssl.key.password = null fetch.max.wait.ms = 500 sasl.kerberos.min.time.before.relogin = 60000 connections.max.idle.ms = 540000 ssl.truststore.password = null session.timeout.ms = 30000 metrics.num.samples = 2 client.id = ssl.endpoint.identification.algorithm = null key.deserializer = class org.apache.kafka.common.serialization.StringDeserializer ssl.protocol = TLS check.crcs = true request.timeout.ms = 40000 ssl.provider = null ssl.enabled.protocols = [TLSv1.2, TLSv1.1, TLSv1] ssl.keystore.location = null heartbeat.interval.ms = 3000 auto.commit.interval.ms = 5000 receive.buffer.bytes = 32768 ssl.cipher.suites = null ssl.truststore.type = JKS security.protocol = PLAINTEXT ssl.truststore.location = null ssl.keystore.password = null ssl.keymanager.algorithm = IbmX509 metrics.sample.window.ms = 30000 fetch.min.bytes = 1 send.buffer.bytes = 131072 auto.offset.reset = latest
