To train model instance, input data are temporarily dumped to a csv file.
This should be improved so that the ML engine reads input data directly from the data source.

// FIXME securely pass training data for ML model training
ResultSet trainingData = getTrainingData(schemaName, tableName, columnNames);
String dataFilename = outputPath + "/data.csv";
FileWriter datafileWriter = new FileWriter(dataFilename);
CSVWriter csvWriter = new CSVWriter(datafileWriter, ',');
csvWriter.writeAll(trainingData, true);
