Brian Beggs commented on HBASE-1064:
------------------------------------
Yeah I've seen it and have been using it. My hope for all of this is to get
this all integrated together, get the wiki page updated and complete with
information for both JSON and XML for the REST interface and kind of tie both
of these implementations together with a more extensible input/output interface.
At least that's the plan. I'm hoping to have alot of this wrapped up in the
coming week or 2.
> HBase REST xml/json improvements
> --------------------------------
>
> Key: HBASE-1064
> URL: https://issues.apache.org/jira/browse/HBASE-1064
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: rest
> Reporter: Brian Beggs
> Attachments: json2.jar, RESTPatch-pass1.patch
>
>
> I've begun work on creating a REST based interface for HBase that can use
> both JSON and XML and would be extensible enough to add new formats down the
> road. I'm at a point with this where I would like to submit it for review
> and to get feedback as I continue to work towards new features.
> Attached to this issue you will find the patch for the changes to this point
> along with a necessary jar file for the JSON serialization. Also below you
> will find my notes on how to use what is finished with the interface to this
> point.
> This patch is based off of jira issues:
> HBASE-814 and HBASE-815
> I am interested on gaining feedback on:
> -what you guys think works
> -what doesn't work for the project
> -anything that may need to be added
> -code style
> -anything else...
> Finished components:
> -framework around parsing json/xml input
> -framework around serialzing xml/json output
> -changes to exception handing
> -changes to the response object to better handle the serializing of output
> data
> -table CRUD calls
> -Full table fetching
> -creating/fetching scanners
> TODO:
> -fix up the filtering with scanners
> -row insert/delete operations
> -individual row fetching
> -cell fetching interface
> -scanner use interface
> Here are the wiki(ish) notes for what is done to this point:
