Apache Spark reassigned SPARK-13242:
------------------------------------
Assignee: Apache Spark
> Moderately complex `when` expression causes code generation failure
> -------------------------------------------------------------------
>
> Key: SPARK-13242
> URL: https://issues.apache.org/jira/browse/SPARK-13242
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: Joe Halliwell
> Assignee: Apache Spark
>
> Moderately complex `when` expressions produce generated code that busts the
> 64KB method limit. This causes code generation to fail.
> Here's a test case exhibiting the problem:
> https://github.com/joehalliwell/spark/commit/4dbdf6e15d1116b8e1eb44822fd29ead9b7d817d
> I'm interested in working on a fix. I'm thinking it may be possible to split
> the expressions along the lines of SPARK-8443, but any pointers would be
> welcome!
