eclipse链接hbase卡住不动

　　最近学习大数据Hadoop和hbase，但是奈何虚拟机速度更不上就想使用Windows下的eclipse链接Linux下的Hadoop等文件，但是使用Hadoop的控件可以连接好，而且也能链接hadoop的相关文件，但是到了hbase就会卡住不动，出现以下界面就一直不动。

经过修改别的虚拟机下的hosts文件什么的都没有解决，最后经过同学的提醒，可能不是我hbase的配置问题，有可能是代码的问题。最终真的发现是代码的问题：

public static void init(){
        configuration  = HBaseConfiguration.create();
        configuration.set("hbase.rootdir","hdfs://192.168.43.18:9000");
        try{
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        }catch (IOException e){
            e.printStackTrace();
        }
    }

这是我之前的代码，但是其中的第二行会出现链接不上hbase（具体问题还在分析）；修改成如下代码就ok：

  public static void init(){
        configuration  = HBaseConfiguration.create();
        configuration.set("hbase.zookeeper.quorum","192.168.43.18");
        configuration.set("hbase.zookeeper.property.clientPort","2181");
        try{
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        }catch (IOException e){
            e.printStackTrace();
        }
    }

运行添加成功！！！（可算成功了）。

 　　注：之上的截图中有一个错误：报错是因为没有给Hadoop安排存储日志文件的位置。

 在程序的src目录下new->others->files创建一个log4j.properties文件，之后在里面添加如下内容，即可；
