Tell which reduce task run which partition
Hi,
Is there a way to tell which Reduce tasks will run which partition? E.g,
I want that reduce task 00000 will read partition 0, reduce task 00001
will read partition 1, etc...
Thanks,

Your example is the reality case. The reducer ID matches its partition
integer.
