> Partitioning discovery will fail with the following case
> {code}
> test("_SUCCESS should not break partitioning discovery") {
>     withTempPath { dir =>
>       val tablePath = new File(dir, "table")
>       val df = (1 to 3).map(i => (i, i, i, i)).toDF("a", "b", "c", "d")
>       df.write
>         .format("parquet")
>         .partitionBy("b", "c", "d")
>         .save(tablePath.getCanonicalPath)
>       Files.touch(new File(s"${tablePath.getCanonicalPath}/b=1", "_SUCCESS"))
>       Files.touch(new File(s"${tablePath.getCanonicalPath}/b=1/c=1", "_SUCCESS"))
>       Files.touch(new File(s"${tablePath.getCanonicalPath}/b=1/c=1/d=1", "_SUCCESS"))
>       checkAnswer(sqlContext.read.format("parquet").load(tablePath.getCanonicalPath), df)
>     }
>   }
> {code}
> Because {{_SUCCESS}} is the in the inner partitioning dirs, partitioning discovery will fail.
