fengchaoge updated SPARK-21337:
-------------------------------
Description:
when there are large 'case when ' expressions in spark sql,the CodeGenerator
failed to compile it.
ERROR INFO:
java.util.concurrent.ExecutionException: java.lang.Exception: failed to
compile: org.codehaus.janino.JaninoRuntimeException: Code of method
"apply_9$(Lorg/apache/spark/sql/catalyst/expressions/GeneratedClass$SpecificUnsafeProjection;Lorg/apache/spark/sql/catalyst/InternalRow;)V"
of class
"org.apache.spark.sql.catalyst.expressions.GeneratedClass$SpecificUnsafeProjection"
grows beyond 64 KB.
It seems like SPARK-13242 has solved this problem in spark-1.6.1,however it
apparence in spark-2.1.1
again。https://issues.apache.org/jira/browse/SPARK-13242.
is there something wrong ?
