cd /usr/local/kafka ./bin/kafka-topics.sh --list --zookeeper 10.1.44.186:2181,10.1.44.187:2181,10.1.44.188:2181 186 187 188 ------------------ ------------------ ------------------ __consumer_offsets __consumer_offsets __consumer_offsets connect-test connect-test connect-test test0320 test0320 test0320
2.创建topic
cd /usr/local/kafka ./bin/kafka-topics.sh --create --zookeeper 10.1.44.186:2181,10.1.44.187:2181,10.1.44.188:2181 --partitions 3 --replication-factor 2 --topic test0326 # 创建后各broker上的物理目录 186 187 188 ---------- ---------- ---------- test0326-1 test0326-1 test0326-1 test0326-2 test0326-2 test0326-2
3.查看指定topic中Leader的信息
cd /usr/local/kafka ./bin/kafka-topics.sh --describe --zookeeper 10.1.44.186:2181,10.1.44.187:2181,10.1.44.188:2181 --topic test0326 Topic: test0326 PartitionCount:3 ReplicationFactor:2 Configs: Topic: test0326 Partition: 0 Leader: 0 Replicas: 0,2 Isr: 0,2 Topic: test0326 Partition: 1 Leader: 1 Replicas: 1,0 Isr: 1,0 Topic: test0326 Partition: 2 Leader: 2 Replicas: 2,1 Isr: 2,1
4.查看consumer组内消费的offset
(1) 使用生产者生成一次
(2) 使用test组消费一次
(3) test组当前的消费偏移
offset = 828 , partition=1, key = 4, value = hh老高4
offset = 829 , partition=1, key = 6, value = hh老高6
offset = 1095, partition=0, key = 1, value = hh老高1
offset = 1096, partition=0, key = 5, value = hh老高5
offset = 1097, partition=0, key = 7, value = hh老高7
offset = 1098, partition=0, key = 8, value = hh老高8
offset = 568 , partition=2, key = 0, value = hh老高0
offset = 569 , partition=2, key = 2, value = hh老高2
offset = 570 , partition=2, key = 3, value = hh老高3
offset = 571 , partition=2, key = 9, value = hh老高9
cd /usr/local/kafka ./bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --zookeeper 10.1.44.186:2181,10.1.44.187:2181,10.1.44.188:2181 --group test --topic test0320 # [2018-03-26 11:06:17,939] WARN WARNING: ConsumerOffsetChecker is deprecated and will be dropped in releases following 0.9.0.
