Vyacheslav Tutrinov updated HDDS-9114:
--------------------------------------
Description:
On uploading a file through s3g an ETag header should be provided:
* in the case of a single file/part upload it represents MD5 of the file content
* if the file will be uploaded using a multipart upload then the ETag of the
object is computed as MD5 of all individual part checksums:
{code}
// e1 = MD5(part-1)
// e2 = MD5(part-2)
// ...
// eN = MD5(part-N)
// ETag = MD5(e1 || e2 || e3 ... || eN) || -N
// For example: ceb8853ddc5086cc4ab9e149f8f09c88-5
{code}
