BJORN A A OLSEN updated HBASE-16299:
------------------------------------
Description:
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.
