https://www.mail-archive.com/dev@spark.apache.org/msg15306.html ,my code is 
```scala
  private val master = "local[*]"
  private val appName = "xqlServerSpark"
  val fileSystem = FileSystem.get()
  val sparkConf = new SparkConf().setMaster(master).
    setAppName(appName).set("spark.sql.warehouse.dir", s"${fileSystem.getUri.toASCIIString}/user/hive/warehouse")
  val   hiveContext = SparkSession.builder().config(sparkConf).enableHiveSupport().getOrCreate().sqlContext
    print(sparkConf.get("spark.sql.warehouse.dir"))
    hiveContext.sql("show tables").show()
