is there a way to write rows sequentially against 60 reduce tasks?

[JunYoung Kim]

hi, 

I run almost 60 ruduce tasks for a single job.

if the outputs of a job are from part00 to part 59.

is there a way to write rows sequentially by sorted keys?

curretly my outputs are like this.

part00)
1
10
12
14

part 01)
2
4
6
11
13

part 02)
3
5
7
8
9

but, my aim is to get the following results.

part00)
1
2
3
4
5

part01)
6
7
8
9
10

part02)
11
12
13
14
15

the hadoop is able to support this kind of one?

thanks
