一. 报错信息
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.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1681) at org.apache.flink.streaming.api.scala.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.scala:688)
二.报错原因
flink1.11版本，移除了flink-streaming-java 对 flink-clients 的依赖，需要手动加入clients依赖。
三.解决方法
在 pom 文件中手动添加依赖即可：
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-clients_2.12</artifactId>
<version>1.11.3</version>
</dependency>
flink1.11报错：java.lang.IllegalStateException: No ExecutorFactory found to execute the application
