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