I will download the latest trunk and give it a try.
I been working on getting a php class written around the REST interface so I
can still use hadoop-streaming
to work with my project.
Good stuff.
Here what I am doing and needed to know the meta info for.
I pull the regions from rest interface for the table I am working with
start one rest scanner for each region
load a map reduce job using hadoop-streaming to process the data from the
scanners
The problem is making sure each map task knows what scanner to use based on
what its local regions are. So there is no data needed to be passed over the
network. Got any suggestions on pulling what the local regions are for a
region server using rest or non java method? If there was a way the rest
could interact with the meta and root tables to get region info that would
be nice.
No support for this yet Billy (HADOOP-2138). Once implemented, I
imagine that it would somehow all be just hidden from you and
hosting regionserver would be doing its best to scan data off adjacent
datanode -- if one were running on same machine.

I just committed Edward Yoon's fix for the below. Also, regards your
comments in HADOOP-2068, try recent TRUNK. HADOOP-2315 should fix the
issue you reported with slashes in rows.
(Stay tuned to this channel for more on answers/fixes to your queries
posted to HADOOP-2068...)

Is there a way to query the meta to tell what server has what region?
I tried select from .META. and -ROOT- but no luck from shell.
Thanks
