Aleksander Eskilson updated SPARK-18118:
----------------------------------------
Description:
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].
