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

>   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")
