> Update REST API scanner with ability to do reverse scan
> -------------------------------------------------------

> Key: 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

> 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.
