有人能帮我编写hadoop脚本吗？基本上，我要做的是填充缺失的年份，以填写每年的数据。我不知道怎样才能恰当地填补这段缺失的岁月。实际数据：

(Zambia, 2004, Health management & support workers, 0.994)
(Zambia, 2005, Health management & support workers, 0.033)
(Zambia, 2006, Health management & support workers, 0.928)
(Zambia, 2009, Health management & support workers, 0.071)
(Zambia, 2010, Health management & support workers, 0.036)

我想要的是：

(Zambia, 2001, Health management & support workers, 0.994)
(Zambia, 2002, Health management & support workers, 0.994)
(Zambia, 2003, Health management & support workers, 0.994)
(Zambia, 2004, Health management & support workers, 0.994)
(Zambia, 2005, Health management & support workers, 0.033)
(Zambia, 2006, Health management & support workers, 0.928)
(Zambia, 2007, Health management & support workers, 0.071)
(Zambia, 2008, Health management & support workers, 0.071)
(Zambia, 2009, Health management & support workers, 0.071)
(Zambia, 2010, Health management & support workers, 0.036)
(Zambia, 2011, Health management & support workers, 0.036)
(Zambia, 2012, Health management & support workers, 0.036)

这是我的密码：
b=负载'/双芯/标称'as(country:chararray, year:int, job:chararray，珀特nthpeople:float); //加载上面显示的数据
c=b组（按国家、职务）；
插入代码>>>
将结果存储到“/dualcore/nomnomready”中；
非常感谢您的帮助。谢谢！
