Kai Zheng commented on HDFS-8430:
---------------------------------
Hi [~szetszwo], would you help confirm the demonstrated approach works or not
to you? Having a unified representation and checksum result across replication,
striping and some other forms as well looks appealing to me in concept. It
helps to tell whether two files are equal or not regardless their block layout
forms. I'd like to get this done and close the gap anyway. Thanks.
