Description

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
