Hitesh Shah commented on TEZ-3454:
----------------------------------
[~darion] The code seems to have a danger of returning negative values. Might
be good to add a test case around this to prove/disprove when using integer.MAX
or long.MAX for the initial value and/or numPartitions.

> Sometimes we just want to use Tez as a framework to process a large volume
> dataset . It's not necessary to collect the same key into a key:value-list
> which maybe cause data skew .
