我写一个火花的工作，尝试使用Scala读取文本文件，下面的工作正常在我的本地机器上。

  VAL MYFILE =myLocalPath / myFile.csv
  对（线474;  -  Source.fromFile（MYFILE）.getLines（））{
    VAL数据= line.split（）
    myHashMap.put（数据（0），数据（1）.toDouble）
  }
 

然后我试图使它在AWS上的工作，我做了以下，但它似乎没有正确读取整个文件。应该用什么有道阅读S3这样的文本文件？非常感谢！

  VAL凭据=新BasicAWSCredentials（的myKey，mySecretKey）;
VAL s3Client =新AmazonS3Client（凭证）;
VAL s3Object = s3Client.getObject（新GetObjectRequest（myBucket，myFile.csv））;

VAL读卡器=新的BufferedReader（新的InputStreamReader（s3Object.getObjectContent（）））;

变种线=
而（（行= reader.readLine（））！= NULL）{
      VAL数据= line.split（）
      myHashMap.put（数据（0），数据（1）.toDouble）
      的println（线）;
}
 

解决方案

我想我得到了它的工作如下图所示：

  VAL s3Object = s3Client.getObject（新GetObjectRequest（myBucket，mypath中/ myFile.csv））;

    VAL myData的= Source.fromInputStream（s3Object.getObjectContent（））。getLines（）
    对（线474;  -  myData的）{
        VAL数据= line.split（）
        myMap.put（数据（0），数据（1）.toDouble）
    }

    的println（我的地图+ myMap.toString（））
 

I am writing a spark job, trying to read a text file using scala, the following works fine on my local machine.

  val myFile = "myLocalPath/myFile.csv"
  for (line <- Source.fromFile(myFile).getLines()) {
    val data = line.split(",")
    myHashMap.put(data(0), data(1).toDouble)
  }

Then I tried to make it work on AWS, I did the following, but it didn't seem to read the entire file properly. What should be the proper way to read such text file on s3? Thanks a lot!

val credentials = new BasicAWSCredentials("myKey", "mySecretKey");
val s3Client = new AmazonS3Client(credentials);
val s3Object = s3Client.getObject(new GetObjectRequest("myBucket", "myFile.csv"));

val reader = new BufferedReader(new InputStreamReader(s3Object.getObjectContent()));

var line = ""
while ((line = reader.readLine()) != null) {
      val data = line.split(",")
      myHashMap.put(data(0), data(1).toDouble)
      println(line);
}

I think I got it work like below:

    val s3Object= s3Client.getObject(new GetObjectRequest("myBucket", "myPath/myFile.csv"));

    val myData = Source.fromInputStream(s3Object.getObjectContent()).getLines()
    for (line <- myData) {
        val data = line.split(",")
        myMap.put(data(0), data(1).toDouble)
    }

    println(" my map : " + myMap.toString())
