Are you sure you have the distributed option set to true?

file system..grrrr

So /etc/hosts changes fixed it so that I have no in the logs
anywhere anymore.  (odd I didn't see that in the docs...I must have

missed that...too bad they don't use NetworkInterfaces.getInterfaces
instead of InetAddress.getLocalHost...can find the real ip 

address easier independent of /etc/hosts).


Now, my client or hbase(not sure which) is still using the local file
system L.  What config am I missing for this to work..(running the
performance example with just 10 rows to see if it works).

Subject: hbase/hadoop config(do I need to change /etc/hosts???)-still
getting in logs


I am trying to run a system with no DNS(they don't have one in this lab
L ).  Hopefully hbase/hadoop should still work fine, correct?


I am having a lot of trouble tracking down why is being used
and why this shows up in hbase master logs...

: Updated ZNode /hbase/rs/1291808309865 with data


I am wondering if I need to tweak my /etc/hosts file?  I am not sure
what java call is being made inside hbase there though.


My /etc/hosts file has(which MATCHES above exactly!!!!
"localhost.localdomain")               localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6


My conf files are pretty simple(and currently-though I would be bad in
production-I am sharing all config files through 

a mount so all nodes mount the one config location...this is just for
ease of changing the files though).  What is wrong with

my config.  (I also share this same config with the client I run who
keeps looking up as well as the master).  Am I 

missing some kind of property override that comes from the defaults?  (I
mean, I see but I tend to think hbase may 

be doing a lookup and I need to fix my /etc/hosts file?)
