尝试在 HBase 上独立运行示例时出现 java.io.EOFException

Question

我正在尝试运行这个示例： 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 shell 可以访问，但是当我尝试运行该示例时，出现以下错误：

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，否则它仍然会将其他库添加到您的类路径中）

我遇到了这个问题，错误日志完全相同，但原因不同。
在我将以下项目添加到 hbase 客户端配置后，它已修复：

<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>
