Kafka创建Topic出现replication factor: 2 larger than available brokers: 0 淘汰replication factor照旧出现错误的办理办法
- kafka-topics.sh --zookeeper hbase:2181 --create --topic ct --partitions 3 --replication-factor 2
[root@hbase kafka]# bin/kafka-topics.sh --zookeeper hbase:2181 --create --topic ct --partitions 3 --replication-factor 2
Error while executing topic command : replication factor: 2 larger than available brokers: 0
[2022-01-16 04:24:57,896] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: replication factor: 2 larger than available brokers: 0
(kafka.admin.TopicCommand$)
错误
出现如许环境是由于kafka的节点只有1个，但是备份却大于1个.以是淘汰备份数量
- kafka-topics.sh --zookeeper hbase:2181 --create --topic ct --partitions 3 --replication-factor 1
出现这种环境
Error while executing topic command : replication factor: 1 larger than available brokers: 0
[2022-01-16 04:26:46,096] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: replication factor: 1 larger than available brokers: 0
这就奇怪了明显已经淘汰了备份数量照旧出现了错误
办理办法
修改创建Topic指令，创建乐成
- kafka-topics.sh --create -zookeeper hbase:2181 --topic ct --partitions 3 --replication-factor 1
