This has a typo in "CDEH" and are also not runnable. I don't see much value
in elaborating this example 3 more times.
(As a related aside, I would like to see less, not more, vendor stuff in
Spark anyway. Adding just this text unduly favors Cloudera a tiny bit; the
alternative is to write a bunch of other vendor combos here, which is going to
turn into at least a maintenance headache. I already disagree with maintaining
vendor versioning info in the project POM.)
