Question

编辑：我能够让它发挥作用。我创建了一个教程来说明如何： http://www.dreamsyssoft.com/blog/blog.php?/archives/5-How-to-use-HBase-Hadoop-Clustered.html

当我设置hbase-site.xml属性时，我可以正常工作：

<name>hbase.rootdir</name>
<value>file:///app/hbase/hbase/</value>

这很好用，它按预期将数据存储在目录中，但我希望它现在连接到我正在运行的hadoop实例而不是使用本地文件。我把它设置为

<value>hdfs://localhost:9000/</value>

而不是本地文件，它将无法正常工作。我是否需要在hadoop端进行一些额外的配置来支持这个？ Hadoop正在运行并使用端口9000。

这是我来自hadoop的core-site.xml：

<configuration>
        <property>
                <name>fs.default.name</name>
                <value>hdfs://localhost:9000</value>
        </property>
</configuration>

这也是尝试在hbase shell中执行“list”时的错误：

hbase(main):001:0> list

Answer 1

我相信Hbase找不到zookeeper仲裁，你必须在hbase-site.xml中设置hbase.zookeeper.quorum属性。还要检查classpath是否设置正确，请检查此doc

http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/mapreduce/package-summary.html#classpath

Answer 2

我使用了http://hbase.apache.org/book.html#zookeeper中建议的配置停止Ipatables并以root模式启动hbase。

Answer 3

可能存在兼容性问题，请检查http://rajkrrsingh.blogspot.in/2013/11/hbase-compatibility-with-hadoop-2x.html

无法让HBase连接到Hadoop
