`

running commands below

server1 on kafka dir, `

./bin/zookeeper-server-start.sh config/zookeeper.properties ./bin/kafka-server-start.sh config/server.properties ./bin/kafka-console-consumer.sh --zookeeper 192.168.50.142:2181 --from-beginning --topic twitter ./bin/kafka-topics.sh --create --zookeeper 192.168.50.142:2181 --replication-factor 1 --partitions 1 --topic twitter

`

and server2 on kafka dir, `

./bin/kafka-console-producer.sh --broker-list 192.168.50.142:9092 --topic twitter

`

and configuration are,

server1(ip: 192.168.50.155):

kafka/config/producer.properties `

metadata.broker.list=192.168.50.142:9092 producer.type=sync compression.codec=none serializer.class=kafka.serializer.defaultencoder

`

server2(ip:192.168.50.142):

kafka/config/zookeeper.properties `

datadir=/tmp/zookeeper clientport=2181 maxclientcnxns=0

`

kafka/config/server.properties `

broker.id=0 listeners=plaintext://0.0.0.0:9092 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=/tmp/kafka-logs num.partitions=1 num.recovery.threads.per.data.dir=1 log.retention.hours=168 log.segment.bytes=1073741824 log.retention.check.interval.ms=300000 log.cleaner.enable=false zookeeper.connect=localhost:2181 zookeeper.connection.timeout.ms=6000 broker.id=0 port=9092 log.dir=/tmp/kafka-logs-1 delete.topic.enable=true

`

kafka.config/consumer.properties `

zookeeper.connect=127.0.0.1:2181 zookeeper.connection.timeout.ms=6000 group.id=test-consumer-group

`

kafka_2.11-0.9.0.0 java 1.8.0_60 node v4.4.4

should need change configuration? please give help.

it seems producer configurations not correct.

kafka/config/producer.properties 

bootstrap.servers=192.168.50.142:9092 key.serializer=org.apache.kafka.common.serialization.stringserializer value.serializer=org.apache.kafka.common.serialization.stringserializer
