该工作包实现的功能：

• HBASE分布式查询，用户输入表名，filter，输出目录等信息查询相应的结果
• 查看HDFS压缩文件文件里面的前几行数据

   public static void main(String[] args) throws Exception {
        Configuration conf = HBaseConfiguration.create();  //建立Configuration
        String[] otherArgs = new GenericOptionsParser(conf, args).getRemainingArgs();  //输入参数parser  
 

参数传递的规则：hadoop jar xxxx.jar program [genericOptions] [commandOptions]
genericOptions:

     -conf <configuration file>     specify a configuration file
     -D <property=value>            use value for given property
     -fs <local|namenode:port>      specify a namenode
     -jt <local|jobtracker:port>    specify a job tracker
     -files <comma separated list of files>    specify comma separated
                            files to be copied to the map reduce cluster
     -libjars <comma separated list of jars>   specify comma separated
                            jar files to include in the classpath.
     -archives <comma separated list of archives>    specify comma
             separated archives to be unarchived on the compute machines.v
