Allen Wittenauer commented on HADOOP-12651:
-------------------------------------------
I think branch-2 lacks the copies the previous versions. Then there is
HADOOP-12798 which probably needs a refresh now.
> Replace dev-support with wrappers to Yetus

> Now that Yetus has had a release, we should rip out the components that make
> it up from dev-support and replace them with wrappers. The wrappers should:
> * default to a sane version
> * allow for version overrides via an env var
> * download into patchprocess
> * execute with the given parameters
> Marking this as an incompatible change, since we should also remove the
> filename extensions and move these into a bin directory for better
> maintenance towards the future.
