我尝试为 hbase 实现这个 spring hadoop 示例
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>
我的 hbase.propertise 文件:
hbase.zk.host=172.30.119.25
hbase.zk.port=2181
我的应用程序上下文.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"

</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,我得到了这个异常:
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
有人可以帮我解决这个异常吗?
