【Flink】问题整理二、flink1.12版本

一、Exception in thread "main" java.lang.IllegalStateException: No ExecutorFactory found to execute the application.

添加 flink-client客户端

<dependency>
  <groupId>org.apache.flink</groupId>
  <artifactId>flink-clients_2.12</artifactId>
  <version>1.12.0</version>
</dependency>

二、java.lang.classNotFoundException: org.apache.flink.api.common.typeinfo.Type@R_328_4045@ion

按装的scala版本要和pom文件的scala版本一致 2.11

 <dependency>
      <groupId>org.apache.flink</groupId>
      <artifactId>flink-streaming-scala_2.11</artifactId>
      <version>1.12.0</version>
      <scope>provided</scope>
    </dependency>

以及加大范围的选择
