    The 'static' keyword cannot be used there in a top level class declaration.
    Please do not ask for code as refusal often offends.

    In other words: the code is broken. Since you know no Java and thus don't know how to fix anything, you're not going to be running this.

    You can't run before you can walk: learn Java like we all had to do. When you are very familiar with Java only then do you start to look into Hadoop.
