> reduce/first-style operations on an
> empty RDD ({{{}RDD.scala{}}}), and re-thrown from {{SafeSparkUDFRunner}} when
> a reduce UDF
> receives no input rows.
> * Introduces a new named structured condition
> {{EMPTY_COLLECTION_NOT_ALLOWED}}
> (SQLSTATE {{{}0A000{}}}), keeping the message text ("empty collection") and
> parameterless
> shape unchanged.
