             Summary: Weird Plan Output when CTE used in RunnableCommand
                 Key: SPARK-18415
                 URL: https://issues.apache.org/jira/browse/SPARK-18415
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.0
            Reporter: Xiao Li
            Assignee: Xiao Li


Currently, when CTE is used in RunnableCommand, the Analyzer does not replace the logical node `With`. The child plan of RunnableCommand is not resolved. However, the output of the `With` plan node looks very confusing.

the plan output looks weird.

ExecutedCommand
   +- CreateViewCommand `w`, WITH w AS (SELECT 1 AS n) SELECT n FROM w, false, false, org.apache.spark.sql.execution.command.PersistedView$@2251b87b
         +- 'With [(w,SubqueryAlias w
               +- Project [1 AS n#16]
                  +- OneRowRelation$
               )]
            +- 'Project ['n]
               +- 'UnresolvedRelation `w`
{code}
