> When uploading a file:
> {code:java}
> long size = 33L * (32L * 1024L * 1024L);
> ByteSource byteSource = TestUtils.randomByteSource().slice(0, size);
> blobStore.createContainerInLocation(null, containerName);
> Blob blob = blobStore.blobBuilder(blobName)
>       .payload(byteSource)
>       .contentLength(size)
>       .build();
> blobStore.putBlob(containerName, blob, PutOptions.Builder.multipart());
> {code}
> I see an error:

> org.jclouds.http.HttpResponseException: command: POST https://www.googleapis.com/storage/v1/b/gaul-blobstore0/o/large-blob/compose HTTP/1.1 failed with response: HTTP/1.1 400 Bad Request; content: [{

> This is due to the wonky {{MultipartUploadSlicingAlgorithm}} slicing into (31) 32 MB parts then creating a remainder 64 MB part that {{BaseBlobStore.putMultipartBlob}} does not account for.  This interface seems stupid and better to create (32) 33 MB parts.  Originally reported at:
