Thanks Tom. Indeed I have a S3 question that need some advise from some S3 experts. To support upload object > 5G, I have used TransferManager.upload to upload object to S3, upload went fine and object are successfully put to S3. However, later on when I am using "s3cmd get <object key>" to retrieve this object, I always got this exception:
"MD5 signatures do not match: computed=Y, received="X" It seems that Amazon S3 kept a different Md5 sum for the multi-part uploaded object. We have been using Riak CS for our S3 testing. If I changed to not using multi-part upload and directly invoking S3 putObject, I will not run into this issue. Do you have such experience before? -min On 6/6/13 1:56 AM, "Thomas O'Dowd" <tpod...@cloudian.com> wrote: >Thanks Min.
