LogicalRelation

case class LogicalRelation(relation: BaseRelation, expectedOutputAttributes: Option[Seq[Attribute]] = scala.None) extends catalyst.plans.logical.LeafNode with MultiInstanceRelation with Product with Serializable

Used to link a BaseRelation in to a logical query plan.

Note that sometimes we need to use LogicalRelation to replace an existing leaf node without changing the output attributes' IDs. The expectedOutputAttributes parameter is used for this purpose. See https://issues.apache.org/jira/browse/SPARK-10741 for more details.
