我正在尝试根据此docker映像来使nutch和hbase工作：https：//hub.docker.com/r/cogfor/netch/
我有一个例外，我尝试注入一个URL文件：
InjectorJob: starting at 2017-12-19 20:49:45
InjectorJob: Injecting urlDir: urls

我知道nutch/hbase/hadoop之间存在一些错误的配置。
我的gora.properties具有：
gora.datastore.default=org.apache.gora.hbase.store.HBaseStore
我的hbase-site.xml具有：
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///data</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>false</value>
</property>
</configuration>
和我的nutch-site.xml具有：
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<!-- Put site-specific property overrides in this file. -->
<configuration>
<property>
<name>http.agent.name</name>

在S.O上多次报告了同样的错误。但是，这些解决方案对我没有用。$ hbase_home和$ hadoop_classpath env变量设置为：
root@a5fb7fefc53e:/nutch_source/runtime/local/bin# echo $HADOOP_CLASSPATH
/opt/hbase-0.98.21-hadoop2/lib/hbase-client-0.98.21-hadoop2.jar:
/opt/hbase-0.98.21-hadoop2/lib/hbase-common-0.98.12-hadoop2.jar:
/opt/hbase-0.98.21-hadoop2/lib/protobuf-java-2.5.0.jar: /opt/hbase-
0.98.21-hadoop2/lib/guava-12.0.1.jar: /opt/hbase-0.98.21-
hadoop2/lib/zookeeper-3.4.6.jar: /opt/hbase-0.98.21-hadoop2/lib/hbase-
protocol-0.98.12-hadoop2.jar
root@a5fb7fefc53e:/nutch_source/runtime/local/bin# echo $HBASE_HOME
/opt/hbase-0.98.21-hadoop2
我验证了所有这些文件的存在。有人可以帮助我失踪的东西吗？
文档中提到了问题（https://wiki.apache.org/nutch/nutch/nutch2tutorial）
" n.b。有可能遇到以下例外：java.lang.noclassdeffounderror：org/apache/hadoop/hbase/hbaseconfiguration;这是由于有时在lib dir中部署在lib dir中的hbase test jar引起的。这只需从您已安装的HBase dir将lib复制到build lib dir中。（目前正在进行此问题）。"
。所有需要完成的就是这样：
cp -R /root/hbase/lib/* /root/nutch/lib/
nutch将开始正常工作。
