Josh Rosen created SPARK-9303:
---------------------------------
Summary: 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
Assignee: 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).
