使用spring data hadoop连接到Cloudera QuickStart VM Hbase时出现未知主机异常

我用

我试图实现这一点

来自主机的示例将连接到VM中的Hbase以创建表、添加数据、读取数据

在我的pom中，我使用

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <spring.version>4.0.5.RELEASE</spring.version>
    <spring.hadoop.version>2.1.2.RELEASE-cdh5</spring.hadoop.version>
    <hadoop.version>2.5.0-cdh5.3.0</hadoop.version>
    <hbase.version>0.98.6-cdh5.3.0</hbase.version>
</properties>

My application-context.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       <context:property-placeholder location="hbase.properties"/>

       <context:component-scan base-package="org.springframework.samples.hadoop.hbase"/>

       <hdp:configuration id="hadoopConfiguration">
              fs.defaultFS=hdfs://172.30.119.25:8020
       </hdp:configuration>

       <hdp:hbase-configuration id="hbaseConfiguration" configuration-ref="hadoopConfiguration" zk-quorum="${hbase.zk.host}" zk-port="${hbase.zk.port}"/>

       <bean id="hbaseTemplate" class="org.springframework.data.hadoop.hbase.HbaseTemplate">
              <property name="configuration" ref="hbaseConfiguration"/>
       </bean>
</beans>

有人能帮我解决此异常吗？

如果您在虚拟机之外运行客户端，请尝试将

quickstart.cloudera

及其外部虚拟机ip添加到

/etc/hosts

中

这些虚拟机通常不是为从外部使用而设计的，但cloudera的虚拟机比hortonwork的虚拟机更友好
