Question

在尝试将融合器用于kafka-connect时出现以下问题。我正在尝试遵循https://www.confluent.io/blog/simplest-useful-kafka-connect-data-pipeline-world-thereabouts-part-1/

上的演示

错误：

./bin/confluent load jdbc_source_mysql_foobar_01 -d /tmp/kafka-connect-jdbc-source.json

}

Answer 1

消息No suitable driver found for意味着找不到正确的jdbc驱动程序。

根据解决上述错误的文章，您需要在share/java/kafka-connect-jdbc中放置适当的jdbc驱动程序

要使用JDBC连接器，您需要为源数据库提供相关的JDBC驱动程序。该连接器随附了PostgreSQL和sqlite的驱动程序-对于所有其他连接器，请下载相应的JAR并将其放置在share / java / kafka-connect-jdbc中。您可以在此处找到有关MySQL，Oracle，SQL Server，DB2和Teradata的相关下载。

复制jar之后，您需要重新启动Kafka Connect
