@pwendel Yes, that's true that that setting doesn't affect spark build,
however, anyone use a jackson library in a spark framework, they always fail
because of different versions between mapper and core of jackson. I don't think
it's not nice and, in my opinion, there are two solutions. One is setting that
pom.xml like that and another one is an exclusion of that library explicitly.
