> Hi, I'm using flink1.12.2 a problem is found when submitting the task of yarn application,
> An example of the Flink official website submitting a task is
> ./bin/flink run-application -t yarn-application ./ examples/streaming/TopSpeedWindowing. jar
> If some of them are misspelled, then yarn-application is written as yarn-appliation
> One C is missing
> Will report an error:
>
> java.lang.IllegalStateException: No ClusterClientFactory found. If you were targeting a Yarn cluster, please make sure to export the HADOOP_CLASSPATH environment variable or have hadoop in your classpath. For more information refer to the "Deployment" section of the official Apache Flink documentation.
>
> BUT
>
> I saw that the code is the 213 line configuration set encapsulated by CliFrontend.java. There is a problem with effectiveconfiguration, resulting in DefaultClusterClientServiceLoader.Java: 83 judgment entry error
>
> Finally, it leads to logical judgment
> if (compatibleFactories.isEmpty()) is true
>
> then
> "No ClusterClientFactory found. If you were targeting a Yarn cluster, "
> + "please make sure to export the HADOOP_CLASSPATH environment variable or have hadoop in your "
> + "classpath. For more information refer to the \"Deployment\" section of the official "
> + "Apache Flink documentation."
>
> Look at all the situations that lead to the failure of the encapsulation of the configuration class,Will prompt HADOOP_CLASSPATH environment 's reason
>
> I think there is something wrong with the description of the error information here, which will lead to misleading. Users mistakenly think it is their own Hadoop_ There is a problem with the classpath environment. I hope you can reply
