-------------------------------------------------------------
I think this issue has not been properly addressed *with* Spark, and should be
reopened.
We are bound by current versions of Hadoop, and can just not simply ignore
users running on top of a Yarn framework. Compatibility with Yarn should take
precedence over unleashing new features. Coordination and compatibility with
Yarn/Hadoop is paramount. We are already building against specific versions of
Hadoop, this should be the case here too, and once the opportunity arises, we
can start supporting Jersey 2 *by choice*. The base of existing intalled Hadoop
Frameworks is just to big.

We are bound by current versions of Hadoop, and can just not simply ignore
users running on top of a Yarn framework. Compatibility with Yarn should take
precedence over unleashing new features. Coordination and compatibility with
Yarn/Hadoop is paramount. What possibly could happen is pushing the hadoop
libraries for jersey in a different namespace - a custom repackaging of the
library. But I guess once you start that, you can as well up the Jersey version.
We are already building against specific versions of Hadoop, this should be the
case here too, and once the opportunity arises, we can start supporting Jersey
2, but Now is not the time.
