Duo Zhang commented on HBASE-17356:
-----------------------------------
In HBASE-21512 we want to replace the old sync client implementation with the
new async client, so we need to support all the features.
Let me support replica get first. Replica scan is another story, which is much
more complicated, as we have a scanner at RS side, which means the scan request
is not idempotent. Need to think more.

> I think we can do better for scan at least as now we will pass the mvcc to
> client. We can use the mvcc to determine if we can get a consistent view when
> reading from replicas other than primary.
