-------------------------------------
Assignee: Kazuyuki Tanimura
> Make ArrowColumnVector Extendable
> ---------------------------------
>
> Key: SPARK-38086
> URL: https://issues.apache.org/jira/browse/SPARK-38086
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Kazuyuki Tanimura
> Assignee: Kazuyuki Tanimura
> Priority: Minor
>
> 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.
