---------------------------------------

             Summary: CTAS fails to resolve when created using saveAsTable
                 Key: SPARK-4825
                 URL: https://issues.apache.org/jira/browse/SPARK-4825
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.2.0
            Reporter: Michael Armbrust
            Assignee: Cheng Hao
            Priority: Critical


While writing a test for a different issue, I found that saveAsTable seems to be broken:

{code}
  test("save join to table") {
    val testData = sparkContext.parallelize(1 to 10).map(i => TestData(i, i.toString))
    sql("CREATE TABLE test1 (key INT, value STRING)")
    testData.insertInto("test1")
    sql("CREATE TABLE test2 (key INT, value STRING)")
    testData.insertInto("test2")
    testData.insertInto("test2")
    sql("SELECT COUNT(a.value) FROM test1 a JOIN test2 b ON a.key = b.key").saveAsTable("test")
    checkAnswer(
      table("test"),
      sql("SELECT COUNT(a.value) FROM test1 a JOIN test2 b ON a.key = b.key").collect().toSeq)
  }
​
    sql("SELECT COUNT(a.value) FROM test1 a JOIN test2 b ON a.key = b.key").saveAsTable("test")
org.apache.spark.sql.catalyst.errors.package$TreeNodeException: Unresolved plan found, tree:
'CreateTableAsSelect None, test, false, None
 Aggregate [], [COUNT(value#336) AS _c0#334L]
  Join Inner, Some((key#335 = key#339))
   MetastoreRelation default, test1, Some(a)
   MetastoreRelation default, test2, Some(b)
{code}
