Apache Spark reassigned SPARK-18118:
------------------------------------
Assignee: (was: Apache Spark)
> SpecificSafeProjection.apply of Java Object from Dataset to JavaRDD Grows
> Beyond 64 KB
> --------------------------------------------------------------------------------------
>
> Key: SPARK-18118
> URL: https://issues.apache.org/jira/browse/SPARK-18118
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Aleksander Eskilson
>
> For sufficiently wide or nested Java Objects, when SpecificSafeProjection
> attempts to recreate the object from an InternalRow, the generated
> SpecificSafeProjection.apply method is larger than allowed:
> {code}
> Caused by: org.codehaus.janino.JaninoRuntimeException: Code of method
> "apply(Ljava/lang/Object;)Ljava/lang/Object;" of class
> "org.apache.spark.sql.catalyst.expressions.GeneratedClass$SpecificSafeProjection"
> grows beyond 64 KB
> {code}
> Although related, this issue appears not to have been resolved by
> SPARK-15285. Since there is only one top-level object when projecting,
> splitExpressions finds no additional Expressions to split. The result is a
> single large, nested Expression that forms the apply code.
> See the reproducer for an example [1].
