problem in starting in Hbase
I have following setup in my hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
</configuration>
but when I started the Hbase I got following error.
ERROR: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able
to connect to ZooKeeper but the connection closes immediately. This could be
a sign that the server has too many connections (30 is the default).
Consider inspecting your ZK server logs for that error and then make sure
you are reusing HBaseConfiguration as often as you can. See HTable's javadoc
for more information.
My OS: Max Lion X
HBase Version : 0.90.4
The above error comes when I have either Hadoop running in sinlge node setup
or it ain't running.

It says connection refused trying to talk to zookeeper (again unrelated to
Hadoop), is zookeeper running? Can you check the log?

Re: problem in starting in Hbase

Guys,
I am struggling from last 3 days to integrate Hbase0.90.4 with Hadoop
0.20.205.0.
And really don't know what is wrong. If either of you help me to run this
then it will be a great help. I am trying to run in pseudo mode and getting
following error.
1. 2011-10-14 14:38:21,382 INFO org.apache.zookeeper.ClientCnxn: Opening
socket connection to server localhost/fe80:0:0:0:0:0:0:1%1:2181
2. 2011-10-14 14:38:21,383 WARN org.apache.zookeeper.ClientCnxn: Session
0x13303b76e500002 for server null, unexpected error, closing socket
connection and attempting reconnect
3. java.net.ConnectException: Connection refused

Have you done what the exception message tells you to do? It's related to
ZooKeeper, not HDFS.
