Herman van Hövell created SPARK-30671:
-----------------------------------------
Summary: SparkSession emptyDataFrame should not create an RDD
Key: SPARK-30671
URL: https://issues.apache.org/jira/browse/SPARK-30671
Project: Spark
Issue Type: New Feature
Components: SQL
Affects Versions: 2.4.4
Reporter: Herman van Hövell
Assignee: Herman van Hövell
SparkSession.emptyDataFrame uses an empty RDD in the background. This is a bit
of a pity because the optimizer can't recognize this as being empty and it
won't apply things like {{PropagateEmptyRelation}}.
