after 3 attempts.
Exceptions:

org.apache.hadoop.hbase.TableNotFoundException: .META.
and when i run list on hbase it give the same error,
my hbase-site.xml is :

Hi Wanli,

I can see that on your logs:

Failed to read: org.apache.zookeeper.KeeperException$NoNodeException:
KeeperErrorCode = NoNode for /hbase/root-region-server

and Read ZNode /hbase/root-region-server got 127.0.0.1:60020

It's connecting locally, no? Do you have your Quorum configured on
your hbase-site.xml

On your master, what is "bin/hbase zkcli" giving?

Hello Wanli,

Have you set the HBASE_MANAGES_ZK property in your hbase-env.sh file
to 'true'? Aslo, I would suggest you to use the latest stable release.

Re: hbase error

wanli gao 2012-11-22, 01:45

hi, Mohammad
i configure hbase according to your wrote, but it give the same error.
Trying to contact region server null for region , row '', but failed
after 3 attempts.
i open RegionServer`s webui,and it `s just one server was running :named
-ROOT-,,0
is it correct that just one server running.is here should run a meta
region server?

Re: hbase error

Mohamed Ibrahim 2012-11-22, 02:04

Hello Wanli,

Try checking /etc/hosts . Make sure that both localhost and <your machine
name> are set to 127.0.0.1, and not 127.0.1.1 . Some distributions do that
and it will sometimes give strange errors.

Hi Wanli,

Somehow, Your ".META." table is having problem. Read more about meta table
here: http://hbase.apache.org/book/arch.catalog.html

Try to do a restart and and see whether it works or not. If not, then look
into the logs of HBase start-up and see if their is any problem reported in
logs.

HTH,
Anil

Also, you might want to run bin/hbase hbck to make sure everything is fine.
