I’m one of the authors.

I think you’ve misunderstood the licenses here, but I am not a lawyer. This
is not legal advice but my understanding is:

1) Spark is Apache licensed so code your make using Spark doesn’t need to
be open source (it’s not GPL)

2) If you want to use examples from the book and you aren’t using a
substantial portion of the code from the book go for it. If you are using a
substantial portion of the code please talk to O’Reilly (the publisher) for
If you look at the book’s example repo you can find information about the
license the individual examples are available under, most are Apache
licensed but some components examples are GPL licensed.

I hope this helps and your able to use the examples in the book to get your
job done and thanks for reading the book.
