Hello All,
I wrote my own partitioner and I would like to see if it's working.
By printing the return of method getPartition I could see that the partitions
were different, but were they really working? To answer that I got the keys
that every reducer task processed and that was what I expected. It seems my
partitioner is working properly. But not easy to discover though.
Does anyone know if there is an easier way to see if your customized
partitioner is working? For instance, a counter that shows how many
partitioners a map generated or a reducer received?
Thanks in advance,
Fabio Almeida
