连接HBase

单线连接HBase
public class HBaseConnection {    
    public static void main(String[] args) throws IOException {
       
        Configuration conf = new Configuration();

    
        conf.set("hbase.zookeeper.quorum","node1.itcast.cn,node2.itcast.cn,node3.itcast.cn");

        
        Connection conn = ConnectionFactory.createConnection(conf);

       
        System.out.println(conn);

       
        conn.close();
    }
}

多线连接HBase

public class HBaseConnection2 {  

    public static Connection conn = null;
    static {
        
        try {
            conn = ConnectionFactory.createConnection();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void closeConnection() throws IOException {
        if(conn != null){
                conn.close();
        }
    }
