使用hbase Java api完成以下操作： 1.建表userfllower 2.用户Mary有一个粉丝Alice，Alice关注列表中也存在Mary 3.用户Jack有两个粉丝Bob和Ben 4.Jack还关注了Mary 5.查看Jack被哪些人关注，Jack关注了谁 6.Bob取关了Jack 7.扫描全表数据

好的，我会根据您的要求进行操作，并不会透露您的要求。

以下是对应的Java API代码实现：

1. 建表userfllower

Configuration config = HBaseConfiguration.create();
Connection connection = ConnectionFactory.createConnection(config);
Admin admin = connection.getAdmin();

HTableDescriptor tableDescriptor = new HTableDescriptor(TableName.valueOf("userfllower"));
tableDescriptor.addFamily(new HColumnDescriptor("follower"));
tableDescriptor.addFamily(new HColumnDescriptor("following"));
admin.createTable(tableDescriptor);

admin.close();
connection.close();

2. 用户Mary有一个粉丝Alice，Alice关注列表中也存在Mary

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Put mary = new Put(Bytes.toBytes("Mary"));
mary.addColumn(Bytes.toBytes("follower"), Bytes.toBytes("Alice"), Bytes.toBytes(""));
mary.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Alice"), Bytes.toBytes(""));

Put alice = new Put(Bytes.toBytes("Alice"));
alice.addColumn(Bytes.toBytes("follower"), Bytes.toBytes("Mary"), Bytes.toBytes(""));
alice.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Mary"), Bytes.toBytes(""));

table.put(mary);
table.put(alice);

table.close();
connection.close();

3. 用户Jack有两个粉丝Bob和Ben

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Put jack = new Put(Bytes.toBytes("Jack"));
jack.addColumn(Bytes.toBytes("follower"), Bytes.toBytes("Bob"), Bytes.toBytes(""));
jack.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Bob"), Bytes.toBytes(""));
jack.addColumn(Bytes.toBytes("follower"), Bytes.toBytes("Ben"), Bytes.toBytes(""));
jack.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Ben"), Bytes.toBytes(""));

table.put(jack);

table.close();
connection.close();

4. Jack还关注了Mary

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Put jack = new Put(Bytes.toBytes("Jack"));
jack.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Mary"), Bytes.toBytes(""));

Put mary = new Put(Bytes.toBytes("Mary"));
mary.addColumn(Bytes.toBytes("follower"), Bytes.toBytes("Jack"), Bytes.toBytes(""));

table.put(jack);
table.put(mary);

table.close();
connection.close();

5. 查看Jack被哪些人关注，Jack关注了谁

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Get getJack = new Get(Bytes.toBytes("Jack"));
Result resultJack = table.get(getJack);

System.out.println("Jack被哪些人关注：");
for(Cell cell : resultJack.getColumnCells(Bytes.toBytes("follower"), Bytes.toBytes(""))){
    System.out.println(Bytes.toString(CellUtil.cloneQualifier(cell)));
}

System.out.println("Jack关注了谁：");
for(Cell cell : resultJack.getColumnCells(Bytes.toBytes("following"), Bytes.toBytes(""))){
    System.out.println(Bytes.toString(CellUtil.cloneQualifier(cell)));
}

table.close();
connection.close();

6. Bob取关了Jack

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Delete delete = new Delete(Bytes.toBytes("Bob"));
delete.addColumn(Bytes.toBytes("following"), Bytes.toBytes("Jack"));

table.delete(delete);

table.close();
connection.close();

7. 扫描全表数据

Connection connection = ConnectionFactory.createConnection(HBaseConfiguration.create());
Table table = connection.getTable(TableName.valueOf("userfllower"));

Scan scan = new Scan();
ResultScanner scanner = table.getScanner(scan);

for(Result result : scanner){
    System.out.println(Bytes.toString(result.getRow()));
    for(Cell cell : result.listCells()){
        String family = Bytes.toString(CellUtil.cloneFamily(cell));
        String qualifier = Bytes.toString(CellUtil.cloneQualifier(cell));
        String value = Bytes.toString(CellUtil.cloneValue(cell));
        System.out.println("\t" + family + ":" + qualifier + " => " + value);
    }
}

scanner.close();
table.close();
connection.close();
