The reason this JIRA is particularly challenging is that the Hadoop project
cannot simultaneously support Jersey 1 and Jersey 2. I am considering
introducing Jersey 2 into Hadoop third-party dependencies and shading the
related paths to ensure that Jersey 1 and Jersey 2 can be introduced into the
Hadoop project simultaneously.

[~slfan1989] IIUC, we need some hacks in class loading mechanism to make JAX-RS
1.1 and 2.0 co-exist as [~aajisaka] mentioned. Since Jersey 1.x and 2.x have
different package name and groupId, we usually don't need relocation for them.
