How to emit multiple keys for the same value?

[HARIPRIYA AYYALASOMAYAJULA]

Hello,

I am facing a problem with implementing this - My mapper should emit
multiple keys for the same value -> for every input (k, v) it should emit
(k, v), (k+1, v),(k+2,v).... (k+n,v).
In MapReduce, it was pretty straight forward - I used a for loop and
performed Context write within that.

This is the code I am using in the map function of MR job:

for (int k = 0; k <  8; k++)

 {

     key = date + ": " + k;

 context.write(new Text(key), new DoubleWritable(value));

   }

  I tried using the map function, but i'm stuck in understanding how I can
use the loop within it.

It would be great if someone can suggest me what could be possible ways to
do it.

Thanks in advance.
