[SOLVED] Writing to a file in S3 from jar on EMR on AWS

Writing to a file in S3 from jar on EMR on AWS

Is there any way in which I can write to a file from my Java jar to an S3 folder where my reduce files would be written ? I have tried something like:

    FileSystem fs = FileSystem.get(conf);
    FSDataOutputStream FS = fs.create(new Path("S3 folder output path"+"//Result.txt"));        

    PrintWriter writer  = new PrintWriter(FS);
    writer.write(averageDelay.toString());
    writer.close();
    FS.close();

Here Result.txt is the new file which I would want to write.

Solution

Answering my own question:-

I found my mistake.I should be passing the URI of S3 folder path to the fileSystem Object like below:-

 FileSystem fileSystem = FileSystem.get(URI.create(otherArgs[1]),conf);
 FSDataOutputStream fsDataOutputStream = fileSystem.create(new Path(otherArgs[1]+"//Result.txt"));      
 PrintWriter writer  = new PrintWriter(fsDataOutputStream);
 writer.write("\n Average Delay:"+averageDelay);
 writer.close();
 fsDataOutputStream.close();
