HBase使用JAVA操作

一、创建Maven项目并添加依赖

	<dependency>
      <groupId>org.apache.hbase</groupId>
      <artifactId>hbase-client</artifactId>
      <version>2.3.5</version>
    </dependency>
    <dependency>
      <groupId>org.apache.hbase</groupId>
      <artifactId>hbase-server</artifactId>
      <version>2.3.5</version>
    </dependency>

二、创建初始化方法与关闭方法

    private static Configuration config = null;
    private static Connection conn = null;

    private static Admin admin = null;
    static {
   
        System.out.println("执行初始化方法");
        config = HBaseConfiguration.create();
        config.set(HConstants.HBASE_DIR,"hdfs://192.168.136.144:9000/hbase");
        config.set(HConstants.ZOOKEEPER_QUORUM,"192.168.136.144");
        config.set(HConstants.CLIENT_PORT_STR,"2181");
        try {
   
            conn = ConnectionFactory.createConnection(config);
            admin = conn.getAdmin();
        } catch (IOException e) {
   
            throw new RuntimeException(e);
        }
    }
    public void close(){
   
        System.out.println("执行close()");
        try {
   
            if (admin!=null){
   
                admin.close()
