根据mysql表中字段创建hbase表

小狼今天很郁闷，我想要mysql中表的字段同步到hbase列族上去，非得在那dos上写命令行，今天想了一个方法，用代码完成

从mysql中获取字段名称

public static String mysql(String biaoming){
		StringBuffer sb = new StringBuffer();
			try {
				new Dbtool();
				Connection conn = Dbtool.getConnection();
				PreparedStatement statement = conn.prepareStatement("desc "+biaoming);
				ResultSet rs = statement.executeQuery();
				while(rs.next()){
					String name = rs.getString(1);
					String leixing = rs.getString(2);
					String isnull = rs.getString(3);
					String suoyin = rs.getString(4);
					sb.append(name+",");
				}
			} catch (Exception e) {
				e.printStackTrace();
			}
			return sb.toString();
	}

用mysql获取的字段创建hbase表

//创建表：
	 public static void createTable(String tableName,String columnFarily)throws Exception{   
		 			System.out.println(columnFarily);
		 try {  
			             HBaseAdmin hBaseAdmin = new HBaseAdmin(con);  
			             if (hBaseAdmin.tableExists(tableName)) {// 如果存在要创建的表，那么先删除，再创�?  
			                 hBaseAdmin.disableTable(tableName);  
			                 hBaseAdmin.deleteTable(tableName);  
			             }  
			             HTableDescriptor tableDescriptor = new HTableDescriptor(tableName);  
			             String[] datas = columnFarily.split(",");
			             for(int i=0;i<datas.length;i++){
			            	 tableDescriptor.addFamily(new HColumnDescriptor(datas[i]));  
			             }
			             hBaseAdmin.createTable(tableDescriptor);  
			             System.out.println("创建表："+tableName+"成功!");
			         } catch (MasterNotRunningException e) {  
			             e.printStackTrace();  
			         } catch (ZooKeeperConnectionException e) {  
			             e.printStackTrace();  
			         } catch (IOException e) {  
			             e.printStackTrace();  
			         }
 
	 }

main方法，运行，创建表

        private static Configuration con; 
	
	private static String mysqlname = "betweens";
	private static String hbasename = "betweens";
	
	
	public static void main(String[] args) throws Exception {
		
        try {  
        	String names = mysql(mysqlname);
        	
        	con =  HBaseConfiguration.create();
        	con.set("hbase.zookeeper.property.clientPort", "2181");
        	con.set("hbase.zookeeper.quorum", "slave1,slave2");
        	con.set("hbase.master", "master:600000");
        	
        	if(names.matches(".*[,]")){
        		names = names.substring(0,names.length()-1);
        		createTable(hbasename,names);
        	}
        } catch (Exception e) {  
            e.printStackTrace();  
        } 


    }
