问题描述

我在尝试将 confluent 用于 kafka-connect 时遇到以下问题.我正在尝试按照 https://www.confluent.io/blog/simplest-useful-kafka-connect-data-pipeline-world-thereabouts-part-1/

I'm getting the below issue while trying to use the confluent for kafka-connect. I'm trying to follow the demo given at https://www.confluent.io/blog/simplest-useful-kafka-connect-data-pipeline-world-thereabouts-part-1/

错误:

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

推荐答案

Message No fit driver found for 表示找不到合适的 jdbc 驱动程序.

Message No suitable driver found for means, that proper jdbc driver cannot be found.

根据文章要修复上述错误，您需要在 share/java/kafka-connect-jdbc

According to article to fix above error you need to place appropriate jdbc driver in share/java/kafka-connect-jdbc

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.连接器附带了 PostgreSQL 和 sqlite 的驱动程序——对于所有其他人，下载适当的 JAR 并将其放在 share/java/kafka-connect-jdbc 中.您可以在此处找到 MySQL、Oracle、SQL Server、DB2 和 Teradata 的相关下载.

To use the JDBC connector, you’ll need to make available the relevant JDBC driver for your source database. The connector ships with drivers for PostgreSQL and sqlite—for all others download the appropriate JAR and place it in share/java/kafka-connect-jdbc. You can find the relevant downloads here for MySQL, Oracle, SQL Server, DB2, and Teradata.

复制jar后，需要重启Kafka Connect

After copying jars, you need to restart Kafka Connect
