hbase meta question

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
Billy

Sorry, it seems to be a shell code's problem.
I'll fix it.

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.

Good stuff.

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.

Can you send me some of the keys you are using? I've been
able to  
test putting slashes in the key with no problems. Are you
certain  
that whatever you're using to URL encode the keys is
correct?
