This might be an issue with the file location in the Spark submit command. Try it with "spark-submit --master spark://master:7077 {file location}"


Check if you've set a name in Application -> Run. If you didn't, the generated XML is gonna have missing information and then this exception will be thrown.


A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.


Needs to add netty-transport-native-epoll with a OS classifier to the classpath, it's not included in netty-all

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
