Apache Spark reassigned SPARK-41498: ------------------------------------ Assignee: (was: Apache Spark) > Union does not propagate Metadata output > ---------------------------------------- > > Key: SPARK-41498 > URL: https://issues.apache.org/jira/browse/SPARK-41498 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.1.2, 3.2.0, 3.1.3, 3.2.1, 3.3.0, 3.2.2, 3.3.1 > Reporter: Fredrik Klauß > Priority: Major > > Currently, the Union operator does not propagate any metadata output. This > makes it impossible to access any metadata if a Union operator is used, even > though the children have the exact same metadata output. > Example: > > {code:java} > val df1 = spark.read.load(path1) > val df2 = spark.read.load(path2) > df1.union(df2).select("_metadata.file_path"). // <-- fails{code} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
