我是Pig的新手 -
猪0.12 Hadoop 1.2.1
我正在编写一本关于Programming Pig的数据集，并且每天下载NYSE数据集。该表看起来像这样 -
daily: {exchange: chararray,symbol: chararray,date: chararray,open: float,high: float,low: float,close: float,volume: float,adj_close: float}
这是我想要实现的目标 -
1）获取上一季度的所有数据，对其进行处理并提供一份报告，其中包含该特定时间段内股票的表现。
这是我做的，现在卡住了 -
daily = load 'NYSE_daily.txt' using PigStorage(',') as (exchange:chararray, symbol:chararray, date:chararray, open:float, high:float , low:float, close:float, volume:float, adj_close:float);
qtr_filter = FILTER daily by date >= '2009-10-01' and date <= '2009-12-31';
qtr_grp = group qtr_filter by date;
当我转储记录时，结果是这样的 -

非常感谢任何帮助。
答案 0 :(得分：0)
我认为你想要做的是：
daily = load 'NYSE_daily.txt' using PigStorage(',') as (exchange:chararray, symbol:chararray, date:chararray, open:float, high:float , low:float, close:float, volume:float, adj_close:float);
qtr_filter = FILTER daily by date >= '2009-10-01' and date <= '2009-12-31';
grouped_by_stock = group qtr_filter by symbol;
输出的每一行都是1个股票代码，并包含该符号的所有每日数据。如果您想要按顺序使用该数据，则必须先订购它。
