示例一：输出表“users”的列族名称

[java]

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;

import org.apache.hadoop.hbase.HBaseConfiguration;

import org.apache.hadoop.hbase.HColumnDescriptor;

import org.apache.hadoop.hbase.HTableDescriptor;

import org.apache.hadoop.hbase.client.HBaseAdmin;

import org.apache.hadoop.hbase.util.Bytes;

public class ExampleClient {

public static void main(String[] args) throws IOException {

Configuration conf = HBaseConfiguration.create();

conf.set("hbase.zookeeper.quorum", "master");//使用eclipse时必须添加这个，否则无法定位

conf.set("hbase.zookeeper.property.clientPort", "2181");

HBaseAdmin admin = new HBaseAdmin(conf);// 新建一个 数据库管理员

HTableDescriptor tableDescriptor = admin.getTableDescriptor(Bytes.toBytes("users"));

byte[] name = tableDescriptor.getName();

System.out.println("result:");

System.out.println("table name: "+ new String(name));

HColumnDescriptor[] columnFamilies = tableDescriptor

.getColumnFamilies();

for(HColumnDescriptor d : columnFamilies){

System.out.println("column Families: "+ d.getNameAsString());

}

}

}

结果：
