Class NativePlaceholder

Object

org.apache.spark.sql.catalyst.trees.TreeNode<PlanType>

org.apache.spark.sql.catalyst.plans.QueryPlan<org.apache.spark.sql.catalyst.plans.logical.LogicalPlan>

org.apache.spark.sql.catalyst.plans.logical.LogicalPlan

org.apache.spark.sql.catalyst.plans.logical.LeafNode

org.apache.spark.sql.catalyst.plans.logical.Command

org.apache.spark.sql.hive.NativePlaceholder

All Implemented Interfaces:

java.io.Serializable, Logging, org.apache.spark.sql.catalyst.trees.LeafNode<org.apache.spark.sql.catalyst.plans.logical.LogicalPlan>, scala.Equals, scala.Product

public class NativePlaceholder
extends org.apache.spark.sql.catalyst.plans.logical.Command
implements scala.Product, scala.Serializable

Used when we need to start parsing the AST before deciding that we are going to pass the command back for Hive to execute natively. Will be replaced with a native command that contains the cmd string.
