使用MyEclipse开发HBase应用程序

当第三方访问HBase的时候，首选需要访问ZooKeeper,因为HBase的重要信息保存在ZooKeeper当中。我们知道，ZooKeeper集群的信息由$$HBASE_HOME/conf/hbase-site.xml文件指定。因此需要通过classpath来指定HBase配置文件的位置，即$HBASE_HOME/conf的位置。
使用HBase客户端进行编程的时候，下文指定的JAR包对于程序来说时必需的。除此之外，commons-configuration slf4j等JAR包也常被用到。下面列出对于hbase-1.2.4版本来说需要的JAR包：

这些包主要来自两个地方： 1.×/hadoop-2.7.1/share/hadoop/common，×/hadoop-2.7.1/share/hadoop/common/lib目录下；
2.×/hbase-1.2.4/lib目录下。
程序中需要的JAR根据错误提示知道对应缺少类对应包通过buildpath添加到IDE中即可。
下面通过一个实例HBaseTestCase Java Project来演示具体的配置。
（1）添加JAR包
添加JAR包有两种方法，比较简单的是，在HBase工程上，右击HBase工程，弹出BuildPath->ConfigureBuildPath,在对话框中单击Libraries选项卡，在该选项卡下单击Add External JARs按钮，定位到$HBase/lib目录下，并选取上述JAR包，如图：

（2）添加hbase-site.xml配置文件
在工程目录下创建Conf文件夹，将$HBase_HOME/conf/目录中的hbase-site.xml文件复制到该文件夹中。通过右键选择Properties->Java BuildPath->Libraries->Add Class Folder,然后勾选Conf文件进行添加。
接下来便可以与普通Java程序一般调用HBase API编写程序了。还可以通过原先HBase Shell与程序操作进行交互。
预备工作在我之前的博客中有介绍，这里就不一一赘述了。首先打开HDFS，然后启动HBase服务。博客地址：伪分布模式下HBase的安装
下面是HBase工程HBaseTestCase Java Project的简单用例即和Hbase shell执行对表的基本操作一直，只不过这里是通过Java代码调用Hbase接口去实现对应功能。
首先介绍一下系统环境：
系统： Ubuntu 16.04
Hadoop：hadoop-2.7.1
HBase：hbase-1.2.4
MyElipse：

MyEclipse Enterprise WorkbenchVersion: 2015 Stable 2.0Build id: 13.0.0-20150518

其次介绍一下项目的结构，如图所示：

下面是程序的完整源码：

5个静态函数和一个主函数。
