kafka的版本为kafka_2.12-2.2.0,zookeeper为3.5.4-beta。
1。启动代理0
./bin/kafka-server-start.sh -daemon config/server.properties
2。创建一个名为test的主题
./bin/kafka-topics.sh --zookeeper 192.168.18.128:2181/kafka --topic test --create --partitions 2 --replication-factor 1
主题测试的描述是
./bin/kafka-topics.sh --zookeeper 192.168.18.128:2181/kafka --topic test --describe
Topic:test PartitionCount:2 ReplicationFactor:1 Configs:
Topic: test Partition: 0 Leader: 0 Replicas: 0 Isr: 0
Topic: test Partition: 1 Leader: 0 Replicas: 0 Isr: 0
3。现在我启动代理1,然后将主题测试的partition-1移到代理1。然后我创建一个名为reassign.json的json文件,reassign.json的内容为
{
"version": 1,
"partitions": [
{
"topic": "test",
"partition": 1,
"replicas": [
1
],
"log_dirs": [
"any"
]
}
]
}
然后我执行命令以移动分区1
./bin/kafka-reassign-partitions.sh --zookeeper 192.168.18.128:2181/kafka --reassignment-json-file json/reassign.json --execute
4。几秒钟后,我执行命令并显示上一条命令的结果。
./bin/kafka-reassign-partitions.sh --zookeeper 192.168.18.128:2181/kafka --verify --reassignment-json-file json/reassign.json
Status of partition reassignment:
Reassignment of partition test-1 is still in progress
我重试了2次,但是对分区的重新分配仍在进行中。
5。然后在server.log中出现以下错误日志。
[2019-09-13 15:37:04,696] ERROR [KafkaApi-0] Error when handling request: clientId=0, correlationId=6, api=UPDATE_METADATA, body={controller_id=0,controller_epoch=1,broker_epoch=62,topic_states=[{topic=test,partition_states=[{partition=1,controller_epoch=1,leader=0,leader_epoch=0,isr=[0],zk_version=0,replicas=[1,0],offline_replicas=[]}]}],live_brokers=[{id=0,end_points=[{port=9092,host=ubuntu,listener_name=PLAINTEXT,security_protocol_type=0}],rack=null},{id=1,end_points=[{port=9092,host=ubuntu,listener_name=PLAINTEXT,security_protocol_type=0}],rack=null}]} (kafka.server.KafkaApis)

有人解决了同样的问题吗?您介意分享您的选择吗?谢谢。
答案 0 :(得分:0)
我尝试了您的配置,对我来说一切都很好。从数字5的错误中,我可以看到VLOOKUP(element, f_range, col_num, true_false)
的副本是partition-1
,而复制因子为1。
基于此处(检查副本):
[1,0]
检查是否在某个地方添加了额外的步骤,以将[2019-09-13 15:37:04,696] ERROR [KafkaApi-0] Error when handling request: clientId=0, correlationId=6, api=UPDATE_METADATA, body={controller_id=0,controller_epoch=1,broker_epoch=62,topic_states=[{topic=test,partition_states=[{partition=1,controller_epoch=1,leader=0,leader_epoch=0,isr=[0],zk_version=0,replicas=[1,0],offline_replicas=[]}]}],live_brokers=[{id=0,end_points=[{port=9092,host=ubuntu,listener_name=PLAINTEXT,security_protocol_type=0}],rack=null},{id=1,end_points=[{port=9092,host=ubuntu,listener_name=PLAINTEXT,security_protocol_type=0}],rack=null}]} (kafka.server.KafkaApis)
添加为broker-1
的副本。
