Jing Zhao commented on HDFS-4167:
---------------------------------
Thanks for the comments, [~vinayrpet]! I will update the patch to address your
comments. Will also add new unit tests and fix remaining bugs.
bq. I see that design document attached is in different approach than the patch
attached. It can be confusing ..
[~rguo], since the design doc is not tightly related to this jira, and has
already been posted in HDFS-6087, I remove it from this jira first. Please feel
free to create separate jiras for new design of snapshots.
