ATTACHMENT ID: 12674611
> DISTRIBUTE BY should work with tez auto-parallelism enabled
> -----------------------------------------------------------
>
> Key: HIVE-8349
> URL: https://issues.apache.org/jira/browse/HIVE-8349
> Project: Hive
> Issue Type: Bug
> Components: Physical Optimizer, Tez
> Affects Versions: 0.14.0
> Reporter: Gopal V
> Assignee: Gopal V
> Fix For: 0.14.0
>
> Attachments: HIVE-8349.1.patch, HIVE-8349.2.patch, HIVE-8349.3.patch
>
>
> 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.
