Duo Zhang commented on HBASE-17167:
-----------------------------------
Anyway, let me revert the clone code and rewrite some UTs first. This patch
could be committed to both master and branch-1. The clone and metrics change
can be done in other issues and maybe 2.0 only.
Thanks.

> For the current implementation, if we use batch or allowPartial when scan,
> then the row level atomic can not be guaranteed if we need to restart a scan
> in the middle of a record due to region move or something else.
> We can return the mvcc used to open scanner to client and client could use
> this mvcc to restart a scan to get row level atomic.
