能写一个Hbase java api测试程序嘛

当然可以，以下是一个简单的HBase Java API测试程序：

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.*;
import org.apache.hadoop.hbase.client.*;
import org.apache.hadoop.hbase.util.Bytes;

import java.io.IOException;

public class HBaseApiTest {
    private static Configuration conf;
    private static Connection connection;
    private static Admin admin;

    public static void main(String[] args) throws IOException {
        // 创建配置对象
        conf = HBaseConfiguration.create();

        // 获取连接
        connection = ConnectionFactory.createConnection(conf);

        // 创建表
        String tableName = "test_table";
        String[] columnFamilies = {"cf1", "cf2"};
        createTable(tableName, columnFamilies);

        // 插入数据
        String rowKey = "row1";
        String columnFamily = "cf1";
        String column = "column1";
        String value = "value1";
        putData(tableName, rowKey, columnFamily, column, value);

        // 查询数据
        getData(tableName, rowKey, columnFamily, column);

        // 删除数据
        deleteData(tableName, rowKey, columnFamily, column);

        // 删除表
        deleteTable(tableName);

        // 关闭连接
        connection.close();
    }

    // 创建表
    private static void createTable(String tableName, String[] columnFamilies) throws IOException {
        // 获取管理员
        admin = connection.getAdmin();

        // 创建表描述符
        HTableDescriptor tableDescriptor = new HTableDescriptor(TableName.valueOf(tableName));

        // 添加列族
        for (String columnFamily : columnFamilies) {
            HColumnDescriptor columnDescriptor = new HColumnDescriptor(columnFamily);
            tableDescriptor.addFamily(columnDescriptor);
        }

        // 创建表
        admin.createTable(tableDescriptor);

        System.out.println("Table " + tableName + " created successfully.");
    }

    // 插入数据
    private static void putData(String tableName, String rowKey, String columnFamily, String column, String value) throws IOException {
        // 获取表
        Table table = connection.getTable(TableName.valueOf(tableName));

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

        // 添加列族、列和值
        put.addColumn(Bytes.toBytes(columnFamily), Bytes.toBytes(column), Bytes.toBytes(value));

        // 插入数据
        table.put(put);

        System.out.println("Data inserted successfully.");
    }

    // 查询数据
    private static void getData(String tableName, String rowKey, String columnFamily, String column) throws IOException {
        // 获取表
        Table table = connection.getTable(TableName.valueOf(tableName));

        // 创建行
        Get get = new Get(Bytes.toBytes(rowKey));

        // 获取指定列族、列的值
        Result result = table.get(get);

        byte[] value = result.getValue(Bytes.toBytes(columnFamily), Bytes.toBytes(column));
        System.out.println("Value retrieved: " + Bytes.toString(value));
    }

    // 删除数据
    private static void deleteData(String tableName, String rowKey, String columnFamily, String column) throws IOException {
        // 获取表
        Table table = connection.getTable(TableName.valueOf(tableName));

        // 创建行
        Delete delete = new Delete(Bytes.toBytes(rowKey));

        // 删除指定列族、列
        delete.addColumn(Bytes.toBytes(columnFamily), Bytes.toBytes(column));

        // 删除数据
        table.delete(delete);

        System.out.println("Data deleted successfully.");
    }

    // 删除表
    private static void deleteTable(String tableName) throws IOException {
        // 获取管理员
        admin = connection.getAdmin();

        // 禁用表
        admin.disableTable(TableName.valueOf(tableName));

        // 删除表
        admin.deleteTable(TableName.valueOf(tableName));

        System.out.println("Table " + tableName + " deleted successfully.");
    }
}

该程序包含了创建表、插入数据、查询数据、删除数据和删除表等常见操作。您可以根据自己的需要进行修改和扩展。
