             Summary: BigInteger Serialization doesn't work with JavaBean Encoder
                 Key: SPARK-41007
                 URL: https://issues.apache.org/jira/browse/SPARK-41007
             Project: Spark
          Issue Type: Bug
          Components: Java API
    Affects Versions: 3.3.1
            Reporter: Daniel Fiterma


When creating a dataset using the [Java Bean Encoder|https://spark.apache.org/docs/3.2.0/api/java/org/apache/spark/sql/Encoders.html#bean-java.lang.Class-] with a bean that contains a field which is a {{java.math.BigInteger}} the dataset will fail to serialize correctly. When trying to deserialize the dataset, Spark throws the following error:

 
{code:java}
Exception in thread "main" org.apache.spark.sql.AnalysisException: Cannot up cast `bigInteger` from struct<> to decimal(38,18).
 {code}
 

 

Reproduction steps:

Using the Java Dataset API:
 # Create a Bean with a  {{java.math.BigInteger}} field
 # Pass said Bean into the Java SparkSession {{createDataset}} function
 #
