[Hadoop-common-user] while loop issue in reduce

Is a_el an ArrayList ?
If not, you only get the last element's value.

Hi

I want to copy the values from the key and Iterator of value input in a reduce function. I was using a ArrayList to copy the list content into. I was using a
while(values.haveNext()) {
a_el=values.next();
}

My input is supposed to have only one key into the reduce with around 625 value elements in the list. I do get the value elements copied but I have all of them with the value of the last element in them.

I think the reduce process processing the list but at the termination of the while loop it is doing something I cannot understand.

I am using version 0.21.0.

Any suggestions?

Thanks a lot
