Abhilash created SPARK-45860:
--------------------------------
Summary: ClassCastException with SerializedLambda in Spark Cluster
Mode
Key: SPARK-45860
URL: https://issues.apache.org/jira/browse/SPARK-45860
Project: Spark
Issue Type: Bug
Components: Spark Core, Spark Submit
Affects Versions: 3.4.1, 3.2.1
Environment: *Environment*
Java Version: 11
Spring Boot Version: 2.7.10
Spark Version: 3.2.1
Reporter: Abhilash
h3. Issue Description
Running a Spark application in cluster mode encounters a
`{*}java.lang.ClassCastException{*}` related to
`j{*}ava.lang.invoke.SerializedLambda{*}`. This issue seems to be specific to
the Spark Cluster mode, and it doesn't occur when running the application
locally without Spring Boot.
h3. Steps to Reproduce
# Create a dummy dataset
{code:java}
Dataset<String> dummyData = spark.createDataset(Arrays.asList("Abhi", "Andrii",
"Rick", "Duc"), Encoders.STRING()); {code}
# Call flatMap function to transform the data
{code:java}
Dataset<TestData> transformedData = dummyData.flatMap(new TestDataFlatMap(),
Encoders.bean(TestData.class)); {code}
# Call any action on the transformed dataset
{code:java}
transformedData.show(); {code}
# Running this Spark application with spark submit command in cluster mode
with Spring Boot results in the mentioned ClassCastException.
h3. *Complete Code:*
{code:java}
@SpringBootApplication(exclude =
{org.springframework.boot.autoconfigure.gson.GsonAutoConfiguration.class})
public class SampleSparkJob{
public static void main(String[] args) {
SpringApplication.run(DataIngestionServiceApplication.class, args);
SparkSession spark = SparkSession.builder()
.appName("SampleSparkJob")
.master("local[*]")
.getOrCreate();
Dataset<String> dummyData = spark.createDataset(Arrays.asList("Abhi",
"Andrii", "Rick", "Duc"), Encoders.STRING());
Dataset<TestData> transformedData = dummyData.flatMap(new
TestDataFlatMap(), Encoders.bean(TestData.class));
transformedData.show();
transformedData.write().mode("append").parquet("outputpath");
spark.stop();
}
}{code}
{code:java}
class TestDataFlatMap implements FlatMapFunction<String, TestData>,
Serializable {
@Override
public Iterator<TestData> call(String name) {
return Arrays.asList(new TestData(name)).iterator();
}
}{code}
{code:java}
@Data
@AllArgsConstructor
public class TestData implements Serializable {
private String name;
} {code}
