[DISCUSS] HADOOP-15983] use jersey-json that is built to use jackson2

[Steve Loughran <st...@cloudera.com.INVALID>]

There's a PR up with a modified version of jersey-json built to use jackson
2, so simplifying our json dependencies

https://github.com/apache/hadoop/pull/3988

the author is an ASF member, so can be trusted as much as the rest of us,
we just have to decide about whether we go with a change which will
complicate the excludes logic of other apps

we are doing this for reload4j,...shall we do the same with jersey?

Hi Steve,

I want to upgrade to Jersey 2.x in
https://issues.apache.org/jira/browse/HADOOP-15984,
but it is very hard and has been pending for several years. Now I'm okay
with using
the modified jersey-json as a temporary workaround.

I think HADOOP-15984 is a blocker to compile Hadoop in JDK 11+,
so it's good that the modified jersey can support JDK 11.

Thanks,
Akira
