>             Project: Hive
>          Issue Type: Bug
>          Components: Spark, Tez
>    Affects Versions: 1.3.0, 1.2.1, 2.0.0, 2.0.1

> SORT BY relies on a transient Random object, which is initialized once per deserialize operation.
> This results in complications during a network partition and when Tez/Spark reuses a cached plan.
