Hello :
I get a problem when I run the Crawl example in the eclipse follow the
RunNutchInEclipse guide
(http://wiki.apache.org/nutch/RunNutchInEclipse#RunNutchInEclipse). Errors will
show below.
My hadoop version is 0.20.2-cdh3u6 and the hbase is 0.90.6-chd3u6 , both are
setted to Pseudo-distributed mode. And they can work well. The nutch version is
2.x, from the SVN (http://svn.apache.org/repos/asf/nutch/branches/2.x).

In my ivy.xml :
<!-- Uncomment this to use HBase as Gora backend. -->
<dependency org="org.apache.gora" name="gora-hbase" rev="0.2"
conf="*->default" />
In my nutch-site.xml:
<property>
<name>storage.data.store.class</name>
<value>org.apache.gora.hbase.store.HBaseStore</value>
<description>Default class for storing data</description>
</property>
<property>
<name>http.agent.name</name>
<value>My Nutch Spider</value>
</property>
The nutch's hbase-site.xml file is copyed from the hbase.
