Apache Spark reassigned SPARK-20253:
------------------------------------
Assignee: Apache Spark
> Remove unnecessary nullchecks of a return value from Spark runtime routines
> in generated Java code
> --------------------------------------------------------------------------------------------------
>
> Key: SPARK-20253
> URL: https://issues.apache.org/jira/browse/SPARK-20253
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Kazuaki Ishizaki
> Assignee: Apache Spark
>
> While we know several Spark runtime routines never return null (e.g.
> {{UnsafeArrayData.toDoubleArray()}}, the generated code by Catalyst always
> checks whether the return value is null or not.
> It is good to remove this nullcheck for reducing Java bytecode size and
> reducing the native code size.
