writeAsCsv

[Lydia Ickler]

Hi, 

stupid question: Why is this not saved to file?

I want to transform an array to a DataSet but the Graph stops at collect().

//Transform Spectrum to DataSet
List<Tuple2<String, String>> dataList = new LinkedList<Tuple2<String, String>>();
double[][] arr = filteredSpectrum.getAs2DDoubleArray();
for (int i=0;i<arr[0].length;i++) {
    dataList.add(new Tuple2( arr[0][i], arr[1][i]));
}
env.fromCollection(dataList).writeAsCsv(output);

Best regards, 

Lydia

Hi, as far as I know only collect, print and execute actually trigger the execution. What you're missing is env.execute() after the writeAsCsv call. Hope this helps.
