             Summary: Accessing canonicalized plan for query with limit throws exception
                 Key: SPARK-21691
                 URL: https://issues.apache.org/jira/browse/SPARK-21691
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Bjoern Toldbod


Accessing the logical, canonicalized plan fails for queries with limits.
The following demonstrates the issue:

{code:java}
val session = SparkSession.builder.master("local").getOrCreate()

// This works
session.sql("select * from (values 0, 1)").queryExecution.logical.canonicalized

// This fails
session.sql("select * from (values 0, 1) limit 1").queryExecution.logical.canonicalized
{code}

The message in the thrown exception is somewhat confusing (or at least not directly related to the limit):
"Invalid call to toAttribute on unresolved object, tree: *"
