flink1.11報錯：java.lang.IllegalStateException: No ExecutorFactory found to execute the application

一. 報錯信息

Exception in thread "main" java.lang.IllegalStateException: No ExecutorFactory found to execute the application.
    at org.apache.flink.core.execution.DefaultExecutorServiceLoader.getExecutorFactory(DefaultExecutorServiceLoader.java:84)
    at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.executeAsync(StreamExecutionEnvironment.java:1803)
    at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1713)
    at org.apache.flink.streaming.api.environment.LocalStreamEnvironment.execute(LocalStreamEnvironment.java:74)
    at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1699)

    at org.apache.flink.streaming.api.scala.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.scala:688)

二.報錯原因

flink1.11版本，移除了flink-streaming-java 對 flink-clients 的依賴，需要手動加入clients依賴。

三.解決方法

在 pom 文件中手動添加依賴即可：

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-clients_2.12</artifactId>
    <version>1.11.3</version>
</dependency>
