使用idea编辑sparkSql的程序运行出现java.lang.IllegalArgumentException: java.net.URISyntaxException

这个是具体错误：

Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: file:D:/idea/work/sparkTest/spark-warehouse

虽然我不知道问什么这么做，但能解决：

var spark=SparkSession.builder().master(“spark://spark02:7077”).appName(“spark_mllib”).config(“spark.sql.warehouse.dir”,”file:///D://test”).getOrCreate()
//需要设置spark.sql.warehouse.dir的路径
