Zack Shoylev commented on JCLOUDS-1064:
---------------------------------------
String eTag = api.getObjectApi(regionId, mpu.containerName()).put(partName,
payload);
long partSize = payload.getContentMetadata().getContentLength();
return MultipartPart.create(partNumber, partSize, eTag);
It seems the etag returned by the put is null, which likely means the upload
(for that specific part) failed.
uploadMultipartPart should probably be more resilient? And avoid throwing an
exception in favor or returning a null etag from putMultipartBlob on fail.
[~gaul], are you working on this? Or do you want me to have a look.

> I am trying to upload a file in chunks to the openstack-swift. Here is the

> blobStore.putBlob("jclouds-example", blob) does work, but if I add multipart
> to the method, then I get NullPointerException: Null partETag.
> ByteSource payload = Files.asByteSource(tempFile);
> Blob blob = blobStore.blobBuilder(objectName)
> .payload(payload)
> .contentDisposition("attachment; filename=dom4j-1.6.1.jar")
> .contentMD5(payload.hash(Hashing.md5()))
> .contentLength(payload.size())
> .contentType(MediaType.OCTET_STREAM.toString())
