Hongze Zhang commented on ARROW-7272:
-------------------------------------

Let's limit the scope of changes into dataset module since we don't yet have a common module for jni utilities.

> Given a C++ std::shared_ptr<RecordBatch>, retrieve it in java as a VectorSchemaRoot class. Gandiva already offer a similar facility but with raw buffers. It would be convenient if users could call C++ that yields RecordBatch and retrieve it in a seamless fashion.
> This would remove one roadblock of using C++ dataset facility in Java.
