[jira] [Created] (SPARK-32018) Fix UnsafeRow set overflowed decimal

Allison Wang created SPARK-32018:
------------------------------------

             Summary: Fix UnsafeRow set overflowed decimal
                 Key: SPARK-32018
                 URL: https://issues.apache.org/jira/browse/SPARK-32018
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0, 2.4.6
            Reporter: Allison Wang


There is a bug that writing an overflowed decimal into UnsafeRow is fine but reading it out will throw ArithmeticException. This exception is thrown when calling {{getDecimal}} in UnsafeRow with input decimal's precision greater than the input precision. Setting the value of the overflowed decimal to null when writing into UnsafeRow should fix this issue.
