I am using spark-sql-2.4.1v in my project with java8.

I need to calculate the quantiles on the some of the (calculated) columns (i.e. con_dist_1 , con_dist_2 ) of below given dataframe df.
{{List<String> calcColmns = Arrays.asList("con_dist_1","con_dist_2")}}
When I am trying to use first version of approxQuantile i.e. approxQuantile(List, List, double) as below

Dataset<Row> df = //dataset
{{List<List<Double>> quants = df.stat().approxQuantile(calcColmns , Array(0.0,0.1,0.5),0.0);}}
*It is giving error :*
{quote}The method approxQuantile(String, double[], double) in the type DataFrameStatFunctions is not applicable for the arguments (List, List, double)
{quote}
so what is wrong here , I am doing it in my eclipseIDE. Why it is not invoking List even though i am passing List ??

Really appreciate any help on this.

more details are added here
