> Following code block reproduces the issue:
> {code}
> df <- createDataFrame(data.frame(x=1))
> f1 <- function(x) x + 1
> f2 <- function(x) f1(x) + 2
> dapplyCollect(df, function(x) { f1(x); f2(x) })
> {code}
> We get following error message:
> {code}
> org.apache.spark.SparkException: R computation failed with
>  Error in f1(x) : could not find function "f1"
> Calls: compute -> computeFunc -> f2
> {code}
> Compare that to this code block with succeeds:
> {code}
> dapplyCollect(df, function(x) { f2(x) })
> {code}
