Key: SPARK-58352
URL: https://issues.apache.org/jira/browse/SPARK-58352
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.2.0
Reporter: Xiao Li
Migrates the legacy error class {{_LEGACY_ERROR_TEMP_3014}} to the structured
error
framework
This error ("empty collection") is a {{SparkUnsupportedOperationException}}
thrown by
{{{}SparkCoreErrors.emptyCollectionError{}}}, raised by RDD 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.
