-----------------------------------------
Summary: 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
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.
