>                 Key: SPARK-6853
>                 URL: https://issues.apache.org/jira/browse/SPARK-6853
>             Project: Spark
>          Issue Type: Bug
>          Components: SparkR
>    Affects Versions: 1.3.0
>            Reporter: Antonio Piccolboni
>            Priority: Major
>              Labels: bulk-closed
>
> I am filling a number of bugs that may be all related but I am not sure and I 
> don't want to forget the test case, so here it is:
> In an R --vanilla session
> library(SparkR)
> sc=sparkR.init()
> z=1
> eval(quote(z), .GlobalEnv)
> collect(lapply(parallelize(sc, 1), function(i) eval(quote(z), .GlobalEnv)))
> Fails not finding z.
> Unfortunately .GlobalEnv gets special treatment (a.k.a the wrong one) when 
> closures are serialized in R and gets replaced by whatever the .Globalenv is 
> at deserialization. It's not so far fetched as a use case since I got here 
> trying to make the foreach package work on Spark.
