2. 原因
pom.xml中某个jar包scala版本与运行环境flink Scala不一致导致的。
比如,我的scala版本是2.12,而用了redis依赖支持的scala版本是2.11
<dependency>
<groupId>org.apache.bahir</groupId>
<artifactId>flink-connector-redis_2.11</artifactId>
<version>1.0</version>
</dependency>
3.解决办法
将redis版本改为1.1.0 (支持scala2.12)文章来源:https://www.toymoban.com/news/detail-502242.html
