stack commented on HBASE-1064:
------------------------------
HColumnDescriptor patch doesn't apply to TRUNK but thats minor fixup on my
part. Would suggest that the REST server print out the port its running on
(but that can be another issue). Its a pity this stuff don't work from the
browser. I get 406 if I browse there but no biggie. I took a quick look at
patch. Looks good to me. I tried it. Was able to do first few curl examples
from wiki page. Results looked like those posted on wiki page.
Sishen, what do you think? If OK with you, if it works with your library, I'd
like to apply this and then open new issues as we find broken stuff?

> 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:
> REST Service for HBASE Notes:
