命令：connect-standalone /grid/1/mukul/confluent-5.0.0/etc/kafka/connect-standalone.properties /grid/1/mukul/confluent-5.0.0/etc/kafka-connect-jdbc/source-quickstart-sqlite.properties

在启动日志中，它清楚地显示了加载 JDBC 连接器：

[2018-08-09 06:59:30,072] INFO Loading plugin from: /grid/1/mukul/confluent-5.0.0/share/java/kafka-connect-jdbc (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader:218)

但它失败并出现以下异常：

Invalid value java.sql.SQLException: No suitable driver found for jdbc:mysql://10.32.177.178:3306/test&user=xxxx&password=xxxx for configuration Couldn't open connection to jdbc:mysql://10.32.177.178:3306/test&user=xxxx&password=xxx

You can also find the above list of errors at the endpoint `/{connectorType}/config/validate`
    at org.apache.kafka.connect.util.ConvertingFutureCallback.result(ConvertingFutureCallback.java:79)
    at org.apache.kafka.connect.util.ConvertingFutureCallback.get(ConvertingFutureCallback.java:66)
    at org.apache.kafka.connect.cli.ConnectStandalone.main(ConnectStandalone.java:110)

也尝试更改插件目录，但没有成功。也尝试将合流共享/*移动到/usr/share/java，但它也不起作用。

Answer 1

1. 从 URL 下载 JAR：https ://dev.mysql.com/downloads/connector/j/5.1.html

2. 放在插件目录内

3. 运行连接

它将开始从 MySql 提取数据。
