我最近开始学习hadoop，
我找到了这个数据集http://stat-computing.org/dataexpo/2009/the-data.html -（2009年数据），
我想要一些建议，如什么样的模式或分析，我可以在hadoopmapreduce做，我只需要一些东西开始，如果有人有一个更好的数据集链接，我可以用来学习，在这里帮助我。
属性如下：

1   Year    1987-2008
2   Month   1-12
3   DayofMonth  1-31
4   DayOfWeek   1 (Monday) - 7 (Sunday)
5   DepTime actual departure time (local, hhmm)
6   CRSDepTime  scheduled departure time (local, hhmm)
7   ArrTime actual arrival time (local, hhmm)
8   CRSArrTime  scheduled arrival time (local, hhmm)
9   UniqueCarrier   unique carrier code
10  FlightNum   flight number
11  TailNum plane tail number
12  ActualElapsedTime   in minutes
13  CRSElapsedTime  in minutes
14  AirTime in minutes
15  ArrDelay    arrival delay, in minutes
16  DepDelay    departure delay, in minutes
17  Origin  origin IATA airport code
18  Dest    destination IATA airport code
19  Distance    in miles
20  TaxiIn  taxi in time, in minutes
21  TaxiOut taxi out time in minutes
22  Cancelled   was the flight cancelled?
23  CancellationCode    reason for cancellation (A = carrier, B = weather, C     = NAS, D = security)
24  Diverted    1 = yes, 0 = no
25  CarrierDelay    in minutes
26  WeatherDelay    in minutes
27  NASDelay    in minutes
28  SecurityDelay   in minutes
29  LateAircraftDelay   in minutes

谢谢
