> Affects Versions: 0.14.0
> Reporter: Gopal V

> Fix For: 0.14.0

>
> Current implementation of DISTRIBUTE BY does not work when tez
> auto-parallelism is turned on, because of hashCode distribution issues.
> In case of distribute by, the key is actually zero bytes, with only
> partitioning enabled via hashCode - this adversely affects the uniform
> hashing implementation.
> In an ideal scenario, the edge should go from the ordered kv input to the
> unordered partitioned edge, to speed up the processing massively.
