             Summary: Support plain text S3 MPU initialization request
                 Key: HDDS-1213
                 URL: https://issues.apache.org/jira/browse/HDDS-1213
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: S3
            Reporter: Elek, Marton
            Assignee: Elek, Marton


S3 Multi-Part-Upload (MPU) is implemented recently in the Ozone s3 gateway. We have extensive testing with using 'aws s3api' application which is passed.

But it turned out that the more simple `aws s3 cp` command fails with _405 Media type not supported error_ message

The root cause of this issue is the JAXRS implementation of the multipart upload method:

{code}
  @POST
  @Produces(MediaType.APPLICATION_XML)
  public Response multipartUpload(
      @PathParam("bucket") String bucket,
      @PathParam("path") String key,
      @QueryParam("uploads") String uploads,
      @QueryParam("uploadId") @DefaultValue("") String uploadID,
      CompleteMultipartUploadRequest request) throws IOException, OS3Exception {
    if (!uploadID.equals("")) {
      //Complete Multipart upload request.
      return completeMultipartUpload(bucket, key, uploadID, request);
    } else {
      // Initiate Multipart upload request.
      return initiateMultipartUpload(bucket, key);
    }
  }
{code}

Here we have a CompleteMultipartUploadRequest parameter which is created by the JAXRS framework based on the media type and the request body. With _Content-Type: application/xml_ it's easy: the JAXRS framework uses the built-in JAXB serialization. But with plain/text content-type it's not possible as there is no serialization support for CompleteMultipartUploadRequest from plain/text.
