Yes, I think it's because Jackson requires some classes which only exist in 
javax.ws.rs-api, which does not bundle into the shaded client.

Have a brief look, js311-api is only required by jersey 1.x? If yes, I think 
upgrading the jersey to 2.x which depends on javax.ws.rs-api and dropping 
js311-api may be the right direction. And I also see that Hadoop 3.3.2 mixed 
use jersey 1.x and 2.x in module hadoop-yarn-applications-catalog-webapp, not 
sure if it's a good practice.

> Spark 3.2.0 depends on Jackson 2.12.3. Let's upgrade to 2.12.5 (2.12.x latest 
> as of now) or upper.
