Summary: 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
Reporter: Duo Zhang
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.
