2. abstract class BaseRelation extends LeafNode

3. abstract class BinaryNode extends LogicalPlan with trees.BinaryNode[LogicalPlan]

   A logical plan node with a left and right child.

4. abstract class Command extends LeafNode

   A logical node that represents a non-query command to be executed by the system.

5. case class Distinct(child: LogicalPlan) extends UnaryNode with Product with Serializable

6. case class ExplainCommand(plan: LogicalPlan) extends Command with Product with Serializable

   Returned by a parser when the users only wants to see what query plan would be executed, without actually performing the execution.

7. case class Filter(condition: Expression, child: LogicalPlan) extends UnaryNode with Product with Serializable

8. case class Generate(generator: Generator, join: Boolean, outer: Boolean, alias: Option[String], child: LogicalPlan) extends UnaryNode with Product with Serializable

   Applies a Generator to a stream of input rows, combining the output of each into a new stream of rows.

9. case class InsertIntoCreatedTable(databaseName: Option[String], tableName: String, child: LogicalPlan) extends UnaryNode with Product with Serializable

10. case class InsertIntoTable(table: LogicalPlan, partition: Map[String, Option[String]], child: LogicalPlan, overwrite: Boolean) extends LogicalPlan with Product with Serializable
