-------------------------------------------
hi team, any updates on this. tried with Spark 3.1.2 and still getting Error:
node stack overflow. looks like this
[https://github.com/apache/spark/pull/26429#discussion_r346103050] was never
addressed?
> SparkR throws node stack overflow
> ---------------------------------
>
> Key: SPARK-34791
> URL: https://issues.apache.org/jira/browse/SPARK-34791
> Project: Spark
> Issue Type: Question
> Components: SparkR
> Affects Versions: 3.0.1
> Reporter: obfuscated_dvlper
> Priority: Major
>
> SparkR throws "node stack overflow" error upon running code (sample below) on
> R-4.0.2 with Spark 3.0.1.
> Same piece of code works on R-3.3.3 with Spark 2.2.1 (& SparkR 2.4.5)
> {code:java}
> source('sample.R')
> myclsr = myclosure_func()
> myclsr$get_some_date('2021-01-01')
> ## spark.lapply throws node stack overflow
> result = spark.lapply(c('2021-01-01', '2021-01-02'), function (rdate) {
> source('sample.R')
> another_closure = myclosure_func()
> return(another_closure$get_some_date(rdate))
> })
> {code}
> Sample.R
> {code:java}
> ## util function, which calls itself
> getPreviousBusinessDate <- function(asofdate) {
> asdt <- asofdate;
> asdt <- as.Date(asofdate)-1;
> wd <- format(as.Date(asdt),"%A")
> if(wd == "Saturday" | wd == "Sunday") {
> return (getPreviousBusinessDate(asdt));
> }
> return (asdt);
> }
> ## closure which calls util function
> myclosure_func = function() {
> myclosure = list()
> get_some_date = function (random_date) {
> return (getPreviousBusinessDate(random_date))
> }
> myclosure$get_some_date = get_some_date
> return(myclosure)
> }
> {code}
> This seems to have caused by sourcing sample.R twice. Once before invoking
> Spark session and another within Spark session.
