> ---------------------------------------------------------------------------------
>
> Key: SPARK-31993
> URL: https://issues.apache.org/jira/browse/SPARK-31993
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.4, 2.4.6, 3.0.0, 3.1.0
> Reporter: Jungtaek Lim
> Priority: Major
>
> https://github.com/apache/spark/blob/a0187cd6b59a6b6bb2cadc6711bb663d4d35a844/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/stringExpressions.scala#L88-L195
> There're three parts of generated code in concat_ws (codes, varargCounts, varargBuilds) and all parts try to split method by itself, while `varargCounts` and `varargBuilds` refer on the generated code in `codes`, hence the overall generated code fails to compile if any of part succeeds to split.
