Subject Re: Important "Undefined Error"
Date Mon, 14 May 2012 14:06:56 GMT
Hi,

There could be multiple issues, but it's strange to have in hbase-site.xml

  <value>hdfs://namenode:9000/hbase</value>

while the core-site.xml says:

<value>hdfs://namenode:54310/</value>

The two entries should match.

I would recommend to:
- use netstat to check the ports (netstat -l)
- do the check recommended by Harsh J previously.

N.
