Hi Stamatis, well I am not building an integration module, I’m more just working on cleanly managing the IoTDB dependencies, that we have dependency convergence (not 10 versions of one lib in the project), that we don’t have duplicate (but different) classes in the classpath and so on.
Especially with the duplicate classes, the shaded (which actually wasn’t really shaded, but more just aggregated, because real shading wouldn’t have caused any problems). But using the “core” classifier resolved most of these problems for me. Chris Von: Stamatis Zampetakis <zabe...@gmail.com> Datum: Dienstag, 19.

Hey Chris, Keep in mind that the core jar was removed some time ago [1, 2] so in new releases (4.0.0 onwards) it will not be there. I am not sure what integration you are trying to establish but it would be definitely easier if you opt for something lighter like the JDBC API and the Hive JDBC driver. Shading in hive-exec is a real pain point [3] but not an easy one to get rid of.
