Apache Spark reassigned SPARK-40380: ------------------------------------ Assignee: Apache Spark > Constant-folding of InvokeLike should not result in non-serializable result > --------------------------------------------------------------------------- > > Key: SPARK-40380 > URL: https://issues.apache.org/jira/browse/SPARK-40380 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.3.0 > Reporter: Kris Mok > Assignee: Apache Spark > Priority: Major > > SPARK-37907 added constant-folding support to the {{InvokeLike}} family of > expressions. Unfortunately it introduced a regression for cases when a > constant-folded {{InvokeLike}} expression returned a non-serializable result. > {{ExpressionEncoder}}s is an area where this problem may be exposed, e.g. > when using sparksql-scalapb on Spark 3.3.0+. > Below is a minimal repro to demonstrate this issue: > {code:scala} > import org.apache.spark.sql.Column > import org.apache.spark.sql.catalyst.analysis.UnresolvedAttribute > import org.apache.spark.sql.catalyst.expressions.Literal > import org.apache.spark.sql.catalyst.expressions.objects.{Invoke, > StaticInvoke} > import org.apache.spark.sql.types.{LongType, ObjectType} > class NotSerializableBoxedLong(longVal: Long) { def add(other: Long): Long = > longVal + other } > case class SerializableBoxedLong(longVal: Long) { def toNotSerializable(): > NotSerializableBoxedLong = new NotSerializableBoxedLong(longVal) } > val litExpr = Literal.fromObject(SerializableBoxedLong(42L), > ObjectType(classOf[SerializableBoxedLong])) > val toNotSerializableExpr = Invoke(litExpr, "toNotSerializable", > ObjectType(classOf[NotSerializableBoxedLong])) > val addExpr = Invoke(toNotSerializableExpr, "add", LongType, > Seq(UnresolvedAttribute.quotedString("id"))) > val df = spark.range(2).select(new Column(addExpr)) > df.collect > {code} > Before SPARK-37907, this example would run fine and result in {{[[42], > [43]]}}. But after SPARK-37907, it'd fail with: > {code:none} > ... > Caused by: java.io.NotSerializableException: NotSerializableBoxedLong > Serialization stack: > - object not serializable (class: NotSerializableBoxedLong, value: > NotSerializableBoxedLong@71231636) > - element of array (index: 1) > - array (class [Ljava.lang.Object;, size 2) > - element of array (index: 1) > - array (class [Ljava.lang.Object;, size 3) > - field (class: java.lang.invoke.SerializedLambda, name: capturedArgs, > type: class [Ljava.lang.Object;) > - object (class java.lang.invoke.SerializedLambda, > SerializedLambda[capturingClass=class > org.apache.spark.sql.execution.WholeStageCodegenExec, > functionalInterfaceMethod=scala/Function2.apply:(Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;, > implementation=invokeStatic > org/apache/spark/sql/execution/WholeStageCodegenExec.$anonfun$doExecute$4$adapted:(Lorg/apache/spark/sql/catalyst/expressions/codegen/CodeAndComment;[Ljava/lang/Object;Lorg/apache/spark/sql/execution/metric/SQLMetric;Ljava/lang/Object;Lscala/collection/Iterator;)Lscala/collection/Iterator;, > > instantiatedMethodType=(Ljava/lang/Object;Lscala/collection/Iterator;)Lscala/collection/Iterator;, > numCaptured=3]) > - writeReplace data (class: java.lang.invoke.SerializedLambda) > - object (class > org.apache.spark.sql.execution.WholeStageCodegenExec$$Lambda$3123/1641694389, > org.apache.spark.sql.execution.WholeStageCodegenExec$$Lambda$3123/1641694389@185db22c) > at > org.apache.spark.serializer.SerializationDebugger$.improveException(SerializationDebugger.scala:41) > at > org.apache.spark.serializer.JavaSerializationStream.writeObject(JavaSerializer.scala:49) > at > org.apache.spark.serializer.JavaSerializerInstance.serialize(JavaSerializer.scala:115) > at > org.apache.spark.util.ClosureCleaner$.ensureSerializable(ClosureCleaner.scala:441) > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
