tip

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

tip

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.

tip

You might've forgot to add a dependency or it's written wrong. Also, you might be using incompatible versions of Java and Hibernate. More on this here: https://goo.gl/SjSlRA

tip

This error means there's a class missing in your classpath during runtime. You need to create a jar with all your dependencies and have it in your classpath. Check Maven Assembly Plugin and how to add your dependencies to a jar: https://goo.gl/U2zr8k

tip

jsp-api and servlet-api jars must NOT be deployed by your web app. They should be marked as provided but not deployed by your app.

tip

The server rejects all jars that already belong to the server runtime (such as tomcat-**.jar, servlet**.jar). Consider substituting the CORS filter you're using for this one: https://goo.gl/ctQ7Fs

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