Description shilpa 2016-07-28 05:04:27 EDT

Description of problem:
Download a S3 multipart upload using swift. Throws Error downloading object: md5sum != etag. But the download is successful though.

Version-Release number of selected component (if applicable):
10.2.2-27

How reproducible:
Always

Steps to Reproduce:
1. Upload a multipart file using S3
2. Download using swift. Throws a failure message but the object download has succeeded.
3. Download file using S3 using 'bucket.get_contentst_to_filename()'. Succeeds

Actual results:

# swift -A http://rgw:80/auth/1.0 -U "testuser:swift" -K "SgmON2jdBWhPFF1xkA69N8F8AghTyadjkATFONbQ" download bucket55 ubuntu
Error downloading object 'bucket55/ubuntu': u'Error downloading ubuntu: md5sum != etag, 17643c29e3c4609818f26becf76d29a3 != d951c7810b12018529b6e79c748b0b31-3'


Looks like a swift issue but not sure. I have only tried with RGW.

Closing NOTABUG because this is expected behavior.
