1、用maven添加依赖（看清自己hbase版本）

<dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-server</artifactId> <version>1.3.1</version></dependency><dependency> <groupId>org.apache.hbase</groupId> <artifactId>hbase-client</artifactId> <version>1.3.1</version></dependency>

2、将虚拟机上的hbase-site.xml文件放到resourcs目录下

3、修改本机的hosts文件（在C:\Windows\System32\drivers\etc下）
添加集群的IP 名称
192.168.124.116 Master
192.168.124.115 Slave1
192.168.124.130 Slave2

4、代码举例，判断表是否存在

package com.zyb.test;import org.apache.hadoop.conf.Configuration;import org.apache.hadoop.hbase.HBaseConfiguration;import org.apache.hadoop.hbase.TableName;import org.apache.hadoop.hbase.client.Admin;import org.apache.hadoop.hbase.client.Connection;import org.apache.hadoop.hbase.client.ConnectionFactory;import java.io.IOException;public class TestDemo { public static Connection connection=null; public static Admin admin=null; static { try { //1、获取配置信息 Configuration configuration = HBaseConfiguration.create(); configuration.set("hbase.rootdir", "hdfs://192.168.124.116:9000/HBase"); configuration.set("hbase.zookeeper.quorum","Master,Slave1,Slave2"); //2、创建连接对象 connection= ConnectionFactory.createConnection(configuration); //3、创建Admin对象 admin = connection.getAdmin(); } catch (IOException e) { e.printStackTrace(); } } //判断表是否存在 public static boolean isTableExiat(String tableName) throws IOException { boolean exists = admin.tableExists(TableName.valueOf(tableName)); return exists; } public static void close(){ if (admin!=null){ try { admin.close(); } catch (IOException e) { e.printStackTrace(); } } if (connection!=null){ try { connection.close(); } catch (IOException e) { e.printStackTrace(); } } } public static void main(String[] args) throws IOException { System.out.println(isTableExiat("student")); //关闭资源 close(); }}
