> Key: HIVE-13108
> URL: https://issues.apache.org/jira/browse/HIVE-13108
> Project: Hive
> Issue Type: Bug
> Components: Spark, Tez
> Affects Versions: 1.3.0, 1.2.1, 2.0.0, 2.0.1
> Reporter: Gopal V

> 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.
