--------------------------------------
+1 for [~maropu]'s action here. Seems there is no related configuration? If
there's an issue against higher branches, let's track it in a new JIRA.
> Hive hash implementation

> Key: SPARK-17495
> URL: https://issues.apache.org/jira/browse/SPARK-17495
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Tejas Patil
> Assignee: Tejas Patil
> Priority: Minor
> Fix For: 2.2.0

> Spark internally uses Murmur3Hash for partitioning. This is different from
> the one used by Hive. For queries which use bucketing this leads to different
> results if one tries the same query on both engines. For us, we want users to
> have backward compatibility to that one can switch parts of applications
> across the engines without observing regressions.
