Writing intermediate key,value pairs to file and read it again
Vikas Jadhav 2013-04-20, 15:43
Hello,
Can anyone help me in following issue
Writing intermediate key,value pairs to file and read it again

let us say i have to write each intermediate pair received @reducer to a
file and again read that as key value pair again and use it for processing

I found IFile.java file which has reader and writer but i am not able
understand how to use it for example. I dont understand Counter value as
last parameter "spilledRecordsCounter"
Thanks.
