-----------------------------------
Summary: Improve error msg if UTF8String concatWs over int length
Key: SPARK-35005
URL: https://issues.apache.org/jira/browse/SPARK-35005
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: ulysses you
We encounter a very extreme case with expression `concat_ws`, and the error msg
is
{code:java}
Caused by: java.lang.NegativeArraySizeException
at org.apache.spark.unsafe.types.UTF8String.concatWs
{code}
Seems the `UTF8String.concat` has already done the length check, so it's better
to add in `concatWs`.
