> 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.
