Send objects larger than 5 Gb using Amazon S3 SDK

Question

I’ve been using the Amazon S3 SDK for cloud server communications for a while, called Dreamhost or Dreamobjects.

My application uses files for my Buckets. However, I started having problems because my files exceeded 5GB, and therefore, I had to change the way to send the file. I followed the documentation provided on the Amazon website (Documentation here).

However, when using this way, I get the following error on the console:

Dec 26, 2016 1:28:22 pm com.amazonaws.services.S3.transfer.Internal.Uploadcallable performAbortMultipartUpload INFO: Unable to abort Multipart upload, you may need to Manually remove uploaded Parts: null (Service: Amazon S3; Status Code: 403; Error Code: Signaturedoesnotmatch; Request ID: tx000000000000f1f16-0058613740-12165497-default) com.amazonaws.services.S3.model.Amazons3exception: null (Service: Amazon S3; Status Code: 403; Error Code: Signaturedoesnotmatch; Request ID: tx000000000000f1f16-0058613740-12165497-default), S3 Extended Request ID: 12165497-default-default

However, I do not know what this "Signature" would be. My information for server access is ok, I checked by third party programs and even on the site itself, so it wouldn’t be login/password/authentication.

I don’t know how to proceed. Anyone with any ideas that could help me? Below, code I’m using.

    try {
         AWSCredentials credentials = new BasicAWSCredentials(UploadBigFile.LOGIN_KEY, UploadBigFile.SECRET_KEY);             
         AmazonS3 conn = new AmazonS3Client(credentials);
         conn.setEndpoint("objects-us-west-1.dream.io");

         final File f = new File("C:\\backup\\packages.rar");             
         ObjectMetadata      metadata    = new ObjectMetadata();                          
         metadata.setContentLength(f.length());
         PutObjectRequest request = new PutObjectRequest(BUCKET_NAME, "FOLDER NAME/cristiano - teste.zip", f);
         request.setGeneralProgressListener(new ProgressListener() {
            long transferidos         = 0L;                
            long transferidosParcial  = 0L;                
            long megaBytes            = 5000000L;
            long timeInicial          = System.currentTimeMillis();
            @Override
            public void progressChanged(ProgressEvent pe) {
                transferidosParcial += pe.getBytesTransferred();
                transferidos        += pe.getBytesTransferred();                                        

                if (transferidosParcial >= megaBytes){
                    long timeFinal            = System.currentTimeMillis() - timeInicial;                                                 
                    int seconds = (int) (timeFinal / 1000) % 60 ;                                                                        

                    double transf       = transferidos/1024/1024;
                    double transParcial = transferidosParcial/1024/1024;
                    double arquivo = f.length()/1024/1024;
                    String tempo = calculeTotalTimeToUpload(seconds, transParcial, arquivo-transf);
                    System.out.println("Transferidos: "+transf+"(MB) de "+arquivo+". "+tempo);
                    transferidosParcial  = 0L;
                    timeInicial          = System.currentTimeMillis();

                }                  
            }
        }); 
        System.out.println("Enviando arquivo. Por favor, aguarde.");
        TransferManager tm = new TransferManager(conn);
        Upload upload = tm.upload(request);
        upload.upload.waitForCompletion();();
        System.out.println("Arquivo enviado com sucesso!");
    } catch (AmazonS3Exception ex) {
        System.out.println("Erro 1");
        ex.printStackTrace();
    } catch (AmazonClientException ex) {
        System.out.println("Erro 2");
        ex.printStackTrace();
    } catch (InterruptedException ex) {
        System.out.println("Erro 3");
        ex.printStackTrace();
    }
