我将quickstart vms用于cdh 5.3.x
我尝试为hbase实现这个spring hadoop示例
该示例将从主机连接到虚拟机中的hbase以创建表、添加数据、读取数据。
在我的pom里我用

<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>

我的hbase.propertise文件:

hbase.zk.host=172.30.119.25
hbase.zk.port=2181

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>

运行示例时,我遇到了以下异常:

Exception in thread "main" org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=35, exceptions:
Wed Jul 15 16:01:24 ICT 2015, org.apache.hadoop.hbase.client.RpcRetryingCaller@35988e16, java.net.UnknownHostException: unknown host: quickstart.cloudera

有人能帮我解决这个例外吗?

如果您在虚拟机之外运行客户端,请尝试添加 quickstart.cloudera 并将其外部虚拟机ip接入 /etc/hosts .
这些虚拟机通常不是为从外部使用而设计的,但是cloudera的虚拟机比hortonwork的虚拟机更友好一些。
