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. Use ConsumerGroupCommand instead. (kafka.tools.ConsumerOffsetChecker$)
Group           Topic                          Pid Offset          logSize         Lag             Owner
test            test0320                       0   1099            1099            0               none
test            test0320                       1   830             830             0               none
test            test0320                       2   572             572             0               none
