Need help on using hbase on EC2
Hi there,
I setup hadoop and hbase on top of EC2 in Pseudo-distributed mode. I
can use hbase shell to connect. However, when I use java client to
connect, I get the following error at client:
12/04/17 10:21:06 INFO zookeeper.RecoverableZooKeeper: The identifier
of this process is 9078@localhost.localdomain
12/04/17 10:21:06 INFO client.ZooKeeperSaslClient: Client will not
SASL-authenticate because the default JAAS configuration section
'Client' could not be found. If you are not using SASL, you may ignore
this. On the other hand, if you expected SASL to work, please fix your
JAAS configuration.
12/04/17 10:21:06 INFO zookeeper.ClientCnxn: Socket connection

In hbase log, I see:

for client /171.69.154.55:60201 which had sessionid 0x136c1355db70006
I have opened EC2 security list for all TCP traffic. I used EC2
private DNS for zk quorum. At client, the private DNS is also used. An
IP to private DNS mapping is added to my /etc/hosts
Can someone please help? I think I'm missing a small thing but
couldn't figure out...
Thanks,
Xin

Would it be possible for you to pastebin a much bigger portion of the
hbase log?
Thx,
