> Some Spark extension libraries need to extend ArrowColumnVector.java. For now, it is impossible as ArrowColumnVector class is final and the accessors are all private.
> For example, Rapids copies the entire ArrowColumnVector class in order to work around the issue
> [https://github.com/NVIDIA/spark-rapids/blob/main/sql-plugin/src/main/java/org/apache/spark/sql/vectorized/rapids/AccessibleArrowColumnVector.java]
> Proposing to relax private/final restrictions to make ArrowColumnVector extendable.
