[jira] [Updated] (SPARK-41007) BigInteger Serialization doesn't work with JavaBean Encoder

     [ https://issues.apache.org/jira/browse/SPARK-41007?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Fiterma updated SPARK-41007:
-----------------------------------
    Description: 
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
