Hi Ted,
Thanks for reminding. This problem has been solved. Now I’m facing another
problem:
When I compile Java class using
javac -cp ‘bin/hbase classpath’ TestHBase.java
Error appears:
BF@node-3:/proj/ucare/bo/hbase-1.0.0 % javac -cp 'bin/hbase classpath'
TestHBase.java
TestHBase.java:1: error: package org.apache.hadoop.conf does not exist

But I have use ‘bin/hbase classpath’ to refer to jars. Do you know what’s the
problem?
Thx so much
Bo

Can you do 'ls /hbase' in zkcli and pastebin the output ?

It seems that zookeeper is running correctly?

I can’t find zkCli.sh. I’m using the zookeeper provided by HBase.
So bad. Should I use my own zookeeper?

Please check zookeeper logs to see if quorum was running fine.
