我正在尝试在S3文件上创建Javardd，但无法创建RDD。有人可以帮助我解决此问题。
代码：
SparkConf conf = new SparkConf().setAppName(appName).setMaster("local");
JavaSparkContext javaSparkContext = new JavaSparkContext(conf);
javaSparkContext.hadoopConfiguration().set("fs.s3.awsAccessKeyId",
accessKey);
javaSparkContext.hadoopConfiguration().set("fs.s3.awsSecretAccessKey",
secretKey);
javaSparkContext.hadoopConfiguration().set("fs.s3.impl",
"org.apache.hadoop.fs.s3native.NativeS3FileSystem");
JavaRDD<String> rawData = sparkContext
.textFile("s3://mybucket/sample.txt");
此代码投掷异常

使用Spark-Submit在本地模式下运行。
我在本地和EC2实例上尝试了此操作，在两种情况下，我都会遇到同样的错误。
应该是 s3n://而不是 s3://
