使用eplicse对hbase进行操作

 测试类

package test1;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HbaseConfiguration;
import org.apache.hadoop.hbase.client.HbaseAdmin;

public class MainHB {
	public static void main(String[] args) {
		try {
			HbaseOp ho = new HbaseOp();
			String[] name = new String[2];
			String tab = "Tab1";
			name[0] = "f1";
			name[1] = "f2";
			ho.createTable(tab, name);

			
			;
			System.out.println("建表成功 OK");
		} catch (Exception e) {
			e.printStackTrace();
		}

		
		  try { HbaseOp ho1=new HbaseOp();
		  ho1.deleteTable("Tab1");
		  System.out.println("删除成功");
		   } 
		  catch(Exception e){ 
			  e.printStackTrace(); 
			  }
		 
	}

}

	admin.close();

	}

public void deleteTable(String strTab)throws Exception

        }
        else if(admin.isTableEnabled(strTab)) {//如果表处于disable
        	 admin.disableTable(strTab);
             admin.deleteTable(strTab);
             System.out.println(strTab + " deleted");
        }
