Spark2.X java.net.URISyntaxException完美解决办法

windows下使用intellij 开发 spark mllib 程序 发现如下错误。

var spark=SparkSession.builder().master("local").appName("test").getOrCreate()

运行时报错：

解决方法：

var spark=SparkSession.builder().master("local").appName("spark_mllib")    .config("spark.sql.warehouse.dir","file:///D://test") //需要设置spark.sql.warehouse.dir的路径   
.getOrCreate()
