Environment :

• Flink version : 1.3
• Flink CDC version: 2.1
• Database and version: oracle12

用官方的例子oracle api 报错，com.ververica.cdc.connectors.oracle.OracleValidator没有实现序列化接口，不能序列化

2.1.0是实现了Serializable接口的，应该是其他问题；

我也出现了同样的问题，已经解决，原因是我的工程里同时还有2.0.0的mysql-connector，有冲突，去掉mysql或者把mysql-connector的版本升到和orcale-connector版本相同，问题就解决了。
