> 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.
