> Tez has many occurrences of jackson dependencies in its dep tree, however
> none of them is direct:
> {code}
> lbodor@HW12459 ~/apache/tez master mvn dependency:tree | grep
> jackson | wc -l
> 204
> {code}
> This is misleading, because tez protobuf history plugin does depend on
> jackson mapper, so it should have jackson as a direct dependency.
> Similarly to other dependencies, transitive deps can also trigger security
> scan alerts, complaining about outdated jackson dependencies. It would be
> cleaner to:
> 1. completely remove unused transitive jackson depdendencies and re-add them
> in test scope where it's needed for clarity's sake
> 2. include jackson as direct dependency where it's used (this could move
> focus to that place when there is a need for an upgrade)
