Maciej Szymkiewicz commented on SPARK-30629:
--------------------------------------------
OK, so I checked and it looks like the problem has been introduced by
SPARK-29777.
> cleanClosure on recursive call leads to node stack overflow
> -----------------------------------------------------------
>
> Key: SPARK-30629
> URL: https://issues.apache.org/jira/browse/SPARK-30629
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Affects Versions: 3.0.0
> Reporter: Maciej Szymkiewicz
> Priority: Major
>
> This problem surfaced while handling SPARK-22817. In theory there are tests,
> which cover that problem, but it seems like they have been dead for some
> reason.
> Reproducible example
> {code:r}
> f <- function(x) {
> f(x)
> }
> newF <- cleanClosure(f)
> {code}
> Just looking at the {{cleanClosure}} / {{processClosure}} pair, that
> function that is being processed is not added to {{checkedFuncs}}.
