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-815 and HBASE-816 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: GET / -retrieves a list of all the tables with their meta data in HBase curl -v -H "Accept: text/xml" -X GET -T - http://localhost:60050/ curl -v -H "Accept: application/json" -X GET -T - http://localhost:60050/ POST / -Create a table curl -H "Content-Type: text/xml" -H "Accept: text/xml" -v -X POST -T - http://localhost:60050/newTable test14 subscription
