wujinhu updated HADOOP-15323:
-----------------------------
Description:
Aliyun OSS will support shallow copy which means server will only copy metadata
when copy object operation occurs.
With shallow copy, we can simple use copyObject api instead of multi-part copy
api if we do not change object storage type & encryption type & source object
is uploaded by Put / Multipart upload api.
So, we will add a flag to indicate whether support shallow copy or not, default
value is true.
