---------------------------------
Summary: Unify the implementation of small scan and regular scan
Key: HBASE-17045
URL: https://issues.apache.org/jira/browse/HBASE-17045
Project: HBase
Issue Type: Sub-task
Components: Client, scan
Affects Versions: 2.0.0, 1.4.0
Reporter: Duo Zhang

But there is another scenario that we need small scan is that, we do not know
the stop row but we only want a small set of results. For example, in the
implementation of region locator, we will use small scan and set caching to 1
as we only need one row.
So I think we need to add a new option(maybe called limit?) for the scan
object, and deprecate the small option. And the server side modification should
also be committed to branch-1 to simplify the logic of async client in 2.0.
