Tejas Patil updated SPARK-17495: -------------------------------- Issue Type: Sub-task (was: Improvement) Parent: SPARK-19256 > Hive hash implementation > ------------------------ > > Key: SPARK-17495 > URL: https://issues.apache.org/jira/browse/SPARK-17495 > Project: Spark > Issue Type: Sub-task > Components: SQL > Reporter: Tejas Patil > Assignee: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
