> From looking into this, we have the following transitive dependencies from
> the hadoop libraries nar:
> - net.java.dev.jets3t:jets3t:jar:0.9.0:compile
> [INFO] | | +- org.apache.httpcomponents:httpclient:jar:4.4.1:compile
> [INFO] | | +- org.apache.httpcomponents:httpcore:jar:4.1.2:compile
> I believe the 4.4.1 of httpclient is coming from the top level pom which has
> a dependency management block that forces the client to 4.4.1 and doesn't for
> core to 4.4.1.
> If we look at httpcore 4.x branch it has the missing Consts class:
> https://github.com/apache/httpcore/tree/4.4.x/httpcore/src/main/java/org/apache/http
> and the 4.1.x branch does not:
> https://github.com/apache/httpcore/tree/4.1.x/httpcore/src/main/java/org/apache/http
> We either need to force both to 4.4.1, or force only the hadoop libraries nar
> to both be 4.1.2 if that is what it normally brings in.
