Question

我在Eclipse中编写了一个程序来测试与HBase的远程连接。这是从HBase Example API Usage修改的。它做了非常基本的事情：连接到hbase，如果存在则删除表，然后创建一个新表。这是代码：

public class TableTest {

    private static Configuration conf = null;

    static{
        conf = HBaseConfiguration.create();
        conf.set("hbase.zookeeper.quorum","192.168.12.120"); 
        conf.set("hbase.zookeeper.property.clientPort","2181"); 
        //conf.set("hbase.master", "192.168.12.120:12000"); // not work

    }

    public static void main(String[] args){
        String tableName = "hbase_table";
        try {
            Connection connection = ConnectionFactory.createConnection(conf);
            Admin admin = connection.getAdmin();
            HTableDescriptor table = new HTableDescriptor(TableName.valueOf(tableName));
            table.addFamily(new HColumnDescriptor("info"));
            if(admin.tableExists(table.getTableName())){
                admin.disableTable(table.getTableName());
                admin.deleteTable(table.getTableName());
            }
            admin.createTable(table);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

但是，我在连接工作方面遇到了一些问题。消息如下。一方面，程序搜索端口16020上192.168.12.120的 HRegionServer ，另一方面，它在端口上的localhost 127.0.0.1搜索 HMaster 12000.这打破了连接，因为HRegionServer和HMaster都在192.168.12.120运行。

那么如何在192.168.12.120设置hbase主控主机？有人可以帮忙吗？这里有两个配置文档：
