Question

在Kafka中创建新主题时，有人知道如何解决此错误吗？

➜  kafka_2.12-2.2.0 bin/kafka-topics.sh --create --bootstrap-server localhost:9093 --replication-factor 2 --partitions 2 --topic user-tracking
Error while executing topic command : org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment.

我已经安装了Java和Maven：

➜  kafka_2.12-2.2.0 mvn --v

我已经开始了Zookeeper： bin/zookeeper-server-start.sh config/zookeeper.properties

我已经启动了server-1： bin/kafka-server-start.sh config/server-1.properties

我确保server-1.properties正在侦听端口9093： listeners=PLAINTEXT://:9093

然后我尝试创建一个主题： bin/kafka-topics.sh --create --bootstrap-server localhost:9093 --replication-factor 2 --partitions 2 --topic user-tracking

您正确配置了listeners。以下应该可以解决问题：

listeners=PLAINTEXT://localhost:9093

在kafka_2.12-2.2.0中创建主题会导致“等待节点分配超时”错误
