----------------------------------------

Note that moving the dataset JNI bridge to use the C data interface is being handled in ARROW-7272.

> *Umbrella ticket for consolidating Java JNI compilation initiative*
> Seems we have spread the JNI code across the {{cpp}} and {{java}} directories. As for other bindings (Python) we already discussed it would be great to consolidate and move all cpp code related to PYthon into PyArrow, we should do something equivalent for Java too and move all C++ code specific to Java into the Java project.
> At the moment there are two JNI related directories:
>  * [https://github.com/apache/arrow/tree/master/java/c]
>  * [https://github.com/apache/arrow/tree/master/cpp/src/jni]
> Let's also research what's the best method to build those. The {{java/c}} directory seems to be already integrated with the Java build process, let's check if that approach is something we can reuse for the {{dataset}} directory too
