win7下本地运行spark以及spark.sql.warehouse.dir设置

  SparkSession spark = SparkSession
                   .builder()
                   .master("local[*]")
                   .enableHiveSupport()
                   .config("spark.sql.warehouse.dir", "file:///E:/git/bigdata_sparkIDE/spark-ide/workspace/functionModule/spark-warehouse")
                   .getOrCreate();

在使用spark2.0的时候遇到如下错误：

// :: INFO SharedState: Warehouse path is 'file:E:\scalacode_v2\Spark2Pro/spark-warehouse'.

google了一下后发现如下解析：

The default value of `spark.sql.warehouse.dir` is `System.getProperty("user.dir")/spark-warehouse`. Since `System.getProperty("user.dir")` is a local dir, we should explicitly set the scheme to local filesystem.
就是说我们需要添加一个配置spark.sql.warehouse.dir，如果不添加上该配置，默认是找的user.dir下面的目录。这个其实是没有的。所以报错。
