[~bslim], yes, the problem will be in a distributed environment, e.g., in Tez, when you have
to send the jar around, right? In your local machine or if you run in a single node mode,
Calcite will be indeed available.

> Currently we are excluding all the jackson core dependencies coming from druid. This
is wrong in my opinion since this will lead to the packaging of unwanted jackson library from
other projects.
> As you can see the file hive-druid-deps.txt currently jacskon core is coming from calcite
and the version is 2.6.3 which is very different from 2.4.6 used by druid. This patch exclude
the unwanted jars and make sure to bring in druid jackson dependency from druid it self.
