Tejas Patil created SPARK-17495:
-----------------------------------
Summary: Hive hash implementation
Key: SPARK-17495
URL: https://issues.apache.org/jira/browse/SPARK-17495
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Tejas Patil
Priority: Minor
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.
