problem starting HBase regional server
Hi,
I have installed the Hadoop/Hbase.
Can you please clarify me the following questions
1) I am having my hmaster running.
when I start my regional server on the other host. I am getting the following Exception.
can you please let me know what I am missing and also how to debug this?
==
sudo /sbin/service hadoop-hbase-regionserver start
starting regionserver, logging to /var/log/hbase/hbase-hbase-regionserver-host123.out

2) My Hadoop is up and running.
But when I try to connect to the Hbase from my BRoswer, I keep getting "connecting" in the status Bar and no response.
I tried: http://10.10.10.11:60010
when I checked Hmaster it is running on 10.10.10.11. but the GUI does not come
3) I have a Hadoop and Hbase installed in 5 hosts.
if I want this to be given to 25 applications for accessing the DB, what are the configuration changes that I should be taken into consideration
like: ( in some applications max handles , threads) similarly what all I should be taken into consideration.
4) when I try to connect to HBase shell
it stops and does not proceed.

Thanks again in advance.

Harsh,
I do have sun java.
also I think all the issues I have listed are inter related ...:(
I can see in the hmaster log that :
2011-12-11 20:22:46,876 INFO org.apache.hadoop.hbase.master.ServerManager: Waiting on regionserver(s) to checkin
2011-12-11 20:22:46,924 INFO org.apache.zookeeper.ClientCnxn: Opening socket connection to server Hostname-namenode.com/10.10.8.11:2181

my hmaster and zookeeper when I do status : show running.
looks zookeeper started with some error??

Seems like you're running GCJ probably, instead of Sun Java. Can you check in that direction, and switch your default java to the proper Sun Java JRE/JDK paths?

Ah no, nevermind that. You do have sun packages in the trace, my bad.
What does 'sudo -u hbase hbase classpath' show?

thank you for the response.
I do have zookeeper.jar?
locate zookeeper.jar
/usr/lib/hbase/lib/zookeeper.jar
/usr/lib/zookeeper/zookeeper.jar
what else I should see to resolve issue (1)
