【kafka】Topic管理

1.查看已經建立的Topic

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.建立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
# 建立後各broker上的物理目錄
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組內消費的offset

(1) 使用生產者生成一次

(2) 使用test組消費一次

(3) test組當前的消費偏移

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

Group           Topic                          Pid Offset          logSize         Lag             Owner
test            test0320                       0   1099            1099            0               none
