Josh Rosen updated SPARK-9303:
------------------------------
Assignee: (was: Josh Rosen)
> Decimal should use java.math.Decimal directly instead of via Scala wrapper
> --------------------------------------------------------------------------
>
> Key: SPARK-9303
> URL: https://issues.apache.org/jira/browse/SPARK-9303
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Reporter: Josh Rosen
>
> Spark SQL's Decimal class should use Java's BigDecimal instead of Scala's,
> since this removes a layer of object allocation and works around an issue
> where Scala's BigDecimal.hashCode() can lead to OOMs (see
> https://issues.scala-lang.org/browse/SI-6173).
