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.
was:Aliyun OSS will support shallow copy which means server will only copy
metadata when copy object operation occurs. So, we will improve copy file for
AliyunOSSFileSystemStore.
