xsys created SPARK-40624:
----------------------------
Summary: A DECIMAL value with division by 0 errors in DataFrame
but evaluates to NULL in SparkSQL
Key: SPARK-40624
URL: https://issues.apache.org/jira/browse/SPARK-40624
Project: Spark
Issue Type: Bug
Components: Spark Shell
Affects Versions: 3.2.1
Reporter: xsys
h3. Describe the bug
Storing an invalid value (e.g. {{{}BigDecimal("1.0/0"){}}}) via {{spark-shell}}
errors out during RDD creation. However, {{1.0/0}} evaluated to {{NULL}} if the
value is inserted into a {{DECIMAL(20,10)}} column of a table via
{{{}spark-sql{}}}.
h3. To Reproduce
On Spark 3.2.1 (commit {{{}4f25b3f712{}}}), using {{{}spark-sql{}}}:
{code:java}
$SPARK_HOME/bin/spark-sql{code}
Execute the following: (evaluated to {{{}NULL{}}})
{code:java}
spark-sql> create table decimal_vals(c1 DECIMAL(20,10)) stored as ORC;
spark-sql> insert into decimal_vals 1.0/0;
spark-sql> select * from ws71;
71 NULL{code}
Using {{{}spark-shell{}}}:
{code:java}
$SPARK_HOME/bin/spark-shell{code}
Execute the following: (errors out during RDD creation)
{code:java}
scala> val rdd = sc.parallelize(Seq(Row(BigDecimal("1.0/0"))))
java.lang.NumberFormatException
at java.math.BigDecimal.<init>(BigDecimal.java:497)
at java.math.BigDecimal.<init>(BigDecimal.java:383)

at scala.math.BigDecimal$.exact(BigDecimal.scala:126)
at scala.math.BigDecimal$.apply(BigDecimal.scala:284)
... 49 elided{code}
h3. Expected behavior
We expect the two Spark interfaces ({{{}spark-sql{}}} & {{{}spark-shell{}}}) to
behave consistently for the same data type & input combination
({{{}BigDecimal{}}}/{{{}DECIMAL(20,10){}}} and {{{}1.0/0{}}}).
