Apache Spark reassigned SPARK-24043:
------------------------------------
Assignee: (was: Apache Spark)
> InterpretedPredicate.eval fails if expression tree contains Nondeterministic
> expressions
> ----------------------------------------------------------------------------------------
>
> Key: SPARK-24043
> URL: https://issues.apache.org/jira/browse/SPARK-24043
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Bruce Robbins
> Priority: Minor
>
> When whole-stage codegen and predicate codegen both fail, FilterExec falls
> back to using InterpretedPredicate. If the predicate's expression contains
> any non-deterministic expressions, the evaluation throws an error:
> {noformat}
> scala> val df = Seq((1)).toDF("a")
> df: org.apache.spark.sql.DataFrame = [a: int]
> scala> df.filter('a > 0).show // this works fine
> 2018-04-21 20:39:26 WARN FilterExec:66 - Codegen disabled for this
> expression:
> (value#1 > 0)
> +---+
> | a|
> +---+
> | 1|
> +---+
> scala> df.filter('a > rand(7)).show // this will throw an error
> 2018-04-21 20:39:40 WARN FilterExec:66 - Codegen disabled for this
> expression:
> (cast(value#1 as double) > rand(7))
> 2018-04-21 20:39:40 ERROR Executor:91 - Exception in task 0.0 in stage 1.0
> (TID 1)
> java.lang.IllegalArgumentException: requirement failed: Nondeterministic
> expression org.apache.spark.sql.catalyst.expressions.Rand should be
> initialized before eval.
> at scala.Predef$.require(Predef.scala:224)
> at
> org.apache.spark.sql.catalyst.expressions.Nondeterministic$class.eval(Expression.scala:326)
> at
> org.apache.spark.sql.catalyst.expressions.RDG.eval(randomExpressions.scala:34)
> {noformat}
> This is because no code initializes the Nondeterministic expressions before
> eval is called on them.
> This is a low impact issue, since it would require both whole-stage codegen
> and predicate codegen to fail before FilterExec would fall back to using
> InterpretedPredicate.
