-----------------------------------
This is not easy, I tried, so let's move it out...
> Use a cell as the start point of a scan internally

> Key: HBASE-17168
> URL: https://issues.apache.org/jira/browse/HBASE-17168
> Project: HBase
> Issue Type: Sub-task
> Components: Client, scan
> Reporter: Duo Zhang
> Priority: Major
> Fix For: 3.0.0

>
> Mainly for restart a scan when error. For now, the logic for reverse scan is
> not stable. You can see the ConnectionUtils.createClosestRowBefore. we just
> append some 0xFF to the end of a key. This works for most time but
> theoretically we could have a row between the given row and the 'closest row
> before'.
> So here I propose we use a cell as the start point of a scan internally as we
> can use createFirstOnRow or createLastOnRow to bettr control the restart
> point.
