如何将pdf/图像存储到HBase表格中

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.Connection;
import org.apache.hadoop.hbase.client.ConnectionFactory;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Table;
import org.apache.hadoop.hbase.util.Bytes;

public class HBaseExample {
    public static void main(String[] args) {
        try {
            // 创建HBase配置
            Configuration config = HBaseConfiguration.create();
            config.set("hbase.zookeeper.quorum", "localhost"); // 设置ZooKeeper地址

            // 创建HBase连接
            Connection connection = ConnectionFactory.createConnection(config);

            // 获取表格对象
            Table table = connection.getTable(TableName.valueOf("your_table_name"));

            // 准备数据
            String rowKey = "your_row_key";
            byte[] pdfBytes = readPDFFile("path_to_pdf_file");

            // 创建Put对象
            Put put = new Put(Bytes.toBytes(rowKey));

            // 添加列族和列
            put.addColumn(Bytes.toBytes("your_column_family"), Bytes.toBytes("your_column"), pdfBytes);

            // 执行插入操作
            table.put(put);

            // 关闭资源
            table.close();
            connection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static byte[] readPDFFile(String filePath) {
        // 读取PDF文件并转换为字节数组
        // 实现代码省略
    }
}
