Confluent架构注册表在启动时失败

Question

Exception in thread "main" java.lang.NoSuchMethodError: io.confluent.rest.Application.parseListeners(Ljava/util/List;ILjava/util/List;Ljava/lang/String;)Ljava/util/List;
at io.confluent.kafka.schemaregistry.storage.KafkaSchemaRegistry.getPortForIdentity(KafkaSchemaRegistry.java:204)
at io.confluent.kafka.schemaregistry.storage.KafkaSchemaRegistry.(KafkaSchemaRegistry.java:133)

等/架构的注册表/ schema-registry.properties

 listeners=http://0.0.0.0:8081 
 kafkastore.connection.url=localhost:2181
 kafkastore.topic=_schemas
 debug=false

kafka和zookeeper已经在运行。

为什么来自zookeeper的日志会继续像

一样

我想知道这可能是架构注册失败的原因。

任何建议。

Answer 1

NoSuchMethodError表示您的CLASSPATH配置错误。

尚不清楚您正在运行的版本或正在使用的操作系统，但是Windows尚未正式受支持，Confluent Platform的pater版本可能已解决了该问题，或者使用Docker映像也可以正常工作

Answer 2

在我的情况下，问题是由主机名引起的，检查主机名是否等于“localhost”

问题“方案注册表在启动时失败”

测试解决方案“将主机名设置为”localhost“”

如果这可以解决您的问题，您可以永久配置主机名：

• 修改文件/ etc / hostname
