yes,my key is ip,and value is a object(which inherited hadoop Record
class,and will be converted
a visualized data),e.g.:
key field1,field2,field3(these are properties belong to
object)
12.121.23.121 121,11,/img/dd.jpg
32.121.23.222 221,11,/img/xx.jpg
1.i want to sort by field1
Your field1 data can be split over multiple reducers. Is it possible to emit
field1 as the key from the reducer (in case you do not need the ip anymore)?
