Work Description: bshashikant commented on pull request #2677:
URL: https://github.com/apache/hadoop/pull/2677#issuecomment-773861987
Appending a timestamp to the deleted snapshot name may lead to different
names being generated pre and post restart of namenode during edit log replay.
Therefore, the idea here is to just append the snapshot Id which will remain
constant.
@szetszwo , can you have a look.

> With ordered snapshot feature turned on, a snapshot will be just marked as
> deleted but won't actually be deleted if its not the oldest one. Since, the
> snapshot is just marked deleted, creation of new snapshot having the same
> name as the one which was marked deleted will fail. In order to mitigate such
> problems, the idea here is to rename the snapshot getting marked as deleted
> by appending deletion timestamp along with snapshot id to it.
