------------------------------------
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.
