----------------------------------
Summary: Row.getAs() return different values in scala and java
Key: SPARK-28368
URL: https://issues.apache.org/jira/browse/SPARK-28368
Project: Spark
Issue Type: Bug
Components: Java API
Affects Versions: 2.4.3
Reporter: Kideok Kim
*description*
* About
[org.apache.spark.sql.Row.getAs()|[https://spark.apache.org/docs/2.4.3/api/java/org/apache/spark/sql/Row.html#getAs-java.lang.String-]],
It doesn't return zero value in java even if I used primitive type null value.
(scala return zero value.) Here is an example with spark ver 2.4.3.
{code:java}
@Test
public void testIntegerTypeNull() {
StructType schema =
createStructType(Arrays.asList(createStructField("test", IntegerType, true)));
Object[] values = new Object[1];
values[0] = null;
Row row = new GenericRowWithSchema(values, schema);
Integer result = row.getAs("test");
System.out.println(result); // result = null
}{code}
* I really appreciate if you confirm whether it is a normal or not.
