Seems something wrong with the inmemory flush feature? [~ram_krish]
> Add inclusive/exclusive support for startRow and endRow of scan
> ---------------------------------------------------------------
>
> Key: HBASE-17320
> URL: https://issues.apache.org/jira/browse/HBASE-17320
> Project: HBase
> Issue Type: Sub-task
> Components: Client, scan
> Affects Versions: 2.0.0
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Fix For: 2.0.0
>
> Attachments: HBASE-17320-v1.patch, HBASE-17320-v2.patch,
> HBASE-17320-v3.patch, HBASE-17320-v4.patch, HBASE-17320.patch
>
>
> This is especially useful when doing reverse scan. HBASE-17168 maybe a more
> powerful solution but we need to be careful about the atomicity, and I do not
> think we will provide the feature to end user. But I think it is OK to
> provide inclusive/exclusive option to end user.
