Subject [jira] Commented: (HADOOP-2068) [hbase] RESTful interface
Date Thu, 08 Nov 2007 17:58:50 GMT

Bryan Duxbury commented on HADOOP-2068:
---------------------------------------

I haven't seen the output of hql.jsp, but I'll try and track it down. You're right, you can't
stick pure binary data in XML, but you can use Base64 encoded binary data. It's a little bigger,
but it cuts down on the number of requests you would have to make, which I think will be the
crucial bottleneck. Of course, single column requests for pure binary data should still be
available.

I agree with your idea of the REST requests redirecting around between the master and the
region servers. That keeps the underlying architecture correct, just with a different  face
on it.

> A RESTful interface would be one means of making hbase accessible to clients that are
not java.  It might look something like the below:
> + An HTTP GET of  http://MASTER:PORT/ outputs the master's attributes: online meta regions,
list of tables, etc.: i.e. what you see now when you go to http://MASTER:PORT/master.jsp.
> + An HTTP GET of http://MASTER:PORT/TABLENAME: 200 if tables exists and HTableDescription
(mimetype: text/plain or text/xml) or 401 if no such table.  HTTP DELETE would drop the table.
 HTTP PUT would add one.
> + An HTTP GET of http://MASTER:PORT/TABLENAME/ROW: 200 if row exists and 401 if not.
> + An HTTP GET of http://MASTER:PORT/TABLENAME/ROW/COLUMNFAMILY: HColumnDescriptor (mimetype:
text/plain or text/xml) or 401 if no such table.
> + An HTTP GET of http://MASTER:PORT/TABLENAME/ROW/COLUMNNAME/: 200 and latest version
(mimetype: binary/octet-stream) or 401 if no such cell. HTTP DELETE would delete the cell.
 HTTP PUT would add a new version.
> + An HTTP GET of http://MASTER:PORT/TABLENAME/ROW/COLUMNNAME/TIMESTAMP: 200 (mimetype:
binary/octet-stream) or 401 if no such cell. HTTP DELETE would remove.  HTTP PUT would put
this record.
> + Browser originally goes against master but master then redirects to the hosting region
server to serve, update, delete, etc. the addressed cell
