아래의 소스로 테스트할때 textFile() 부분에서 java.net.URISyntaxException가 발생하는데 이때는

아래 주석부분에 있는것처럼 sparkConf.set("spark.sql.warehouse.dir", "file:///tmp/spark-warehouse"); 를 추가하여 준다.

---------테스트 소스중 일부 --------

SparkConf sparkConf=new SparkConf().setAppName("SparkJavaTest");
   sparkConf.setMaster("local[*]");
   //sparkConf.set("spark.sql.warehouse.dir", "file:///tmp/spark-warehouse");

   JavaSparkContext ctx=new JavaSparkContext(sparkConf);
   SQLContext sqlContext = new SQLContext(ctx);       

   JavaRDD<String> dataCollection=ctx.textFile("file:///C:/tmp/sparktest/a.txt");
