Question

我正在尝试运行此示例：https://github.com/larsgeorge/hbase-book/blob/master/ch03/src/main/java/client/PutExample.java，来自本书：http://ofps.oreilly.com/titles/9781449396107/，在独立的HBase安装上。启动HBase工作正常并且可以访问shell，但是当我尝试运行该示例时，我收到以下错误：

提前致谢。

Answer 1

问题是我使用较新版本的HBase编译了这些示例。要修复此错误，对于这些示例，请编辑pom.xml并确保HBase依赖项与您正在运行的版本相同并再次构建。（另外不要忘记删除chXX / target / cached_classpath.txt，否则它仍会将其他库添加到类路径中）

Answer 2

我用完全相同的错误日志遇到了这个问题，但不同的原因。我将以下项目添加到hbase客户端配置后修复：

＆＃13;

<property>
    <name>hbase.security.authentication</name>
    <value>kerberos</value> 
</property> 
<property>
     <name>hbase.rpc.engine</name>
     <value>org.apache.hadoop.hbase.ipc.SecureRpcEngine</value>
</property>

＆＃13;

尝试在HBase独立运行示例时尝试java.io.EOFException
