The example is out of date with respect to current Vector class. The
zeros() method is on "Vectors". There is not currently a += operation
for Vector anymore.
To be fair the example doesn't claim this illustrates use of the Spark
Vector class but it did work with the now-deprecated Vector.
Make sure you still have AccumulableParam imported.
You could make a PR to adjust the example to something that works with
the newer class once you have it working.
