You need to be added in the User's list to get assigned to this project. Let's see if I can
add you to the project if not will see what can be done.

> Update REST API scanner with ability to do reverse scan
> -------------------------------------------------------
>                 Key: HBASE-16299
>                 URL: https://issues.apache.org/jira/browse/HBASE-16299
>             Project: HBase
>          Issue Type: Improvement
>          Components: REST
>    Affects Versions: 1.1.2
>         Environment: Not environment specific (tested on HDP 2.4.2)
>            Reporter: Bjorn Olsen
>            Priority: Minor
> HBASE-4811 "Support reverse scan" was implemented from version 0.98.0, and is available
in the Java API.
> However this functionality is not yet exposed via REST.
> Example of expected API call:
> http://server:port/table/*?startrow=1&endrow=10&reversed=true"
> (Returns rows ordered by key in reverse, eg from 9*** to 1*** )
> Based on my (limited) understanding this should be simple to add.
> See org.apach.hadoop.hbase.rest.TableResource.getScanResource
> This function creates a Scan object with parameters passed in from the REST API (I assume).

> Adding this functionality may be as simple as adding a "reversed" parameter to the REST
API which passes down to where the Scan object is created in TableResource.getScanResource.
