Hyukjin Kwon updated SPARK-15258: --------------------------------- Labels: bulk-closed (was: ) > Nested/Chained case statements generate codegen over 64k exception > ------------------------------------------------------------------ > > Key: SPARK-15258 > URL: https://issues.apache.org/jira/browse/SPARK-15258 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 1.6.1 > Reporter: Jonathan Gray > Priority: Major > Labels: bulk-closed > Attachments: NestedCases.scala > > > Nested/Chained case-when expressions generate a codegen goes beyound 64k > exception. > A test attached demonstrates this behaviour. > I'd like to try and fix this but don't really know the best place to start. > Ideally, I'd like to avoid the codegen fallback as with large volumes this > hurts performance. > This is similar(ish) to SPARK-13242 but I'd like to see if there are any > alternatives to the codegen fallback approach. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
