Evan Chan created SPARK-3295:
--------------------------------
Summary: [Spark SQL] schemaRdd1 ++ schemaRdd2 does not return
another SchemaRdd
Key: SPARK-3295
URL: https://issues.apache.org/jira/browse/SPARK-3295
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.0.2
Reporter: Evan Chan
Priority: Minor
Right now,
schemaRdd1.unionAll(schemaRdd2) returns a SchemaRdd.
However,
schemaRdd1 ++ schemaRdd2 returns an RDD[Row].
Similarly,
schemaRdd1.union(schemaRdd2) returns an RDD[Row].
This is inconsistent. Let's make ++ and union have the same behavior as
unionAll.
Actually, not sure there needs to be both union and unionAll.
