Deleting files from HDFS | Scala - scala

Question

I am trying to delete files that are more than two hours old. To do this i am trying the following:
import java.util.Date
import org.apache.hadoop.fs.Path
import org.apache.hadoop.fs.FileSystem
import java.text.SimpleDateFormat
def cleaningHDFS(path: String) = {
//Actual Date
val fechaActual = new Date()
//2h less
var millisec_byDay = 1000 * 60 * 60
var fechaActualMenosDos = new Date(fechaActual.getTime() - (millisec_byDay * 1))
var fechaDef = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(fechaActualMenosDos)
//Hasta aquí se obtiene la fecha actual menos dos días
val conf = spark.sparkContext.hadoopConfiguration;
val fs = FileSystem.get(conf);
val dirPath = new Path(path);
val filestatus = fs.listFiles(dirPath);
val df:SimpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")
//Deleting files
println(fechaDef)
filestatus.foreach(f =>
if(df.format(f.getModificationTime) < fechaDef) {
println(df.format(f.getModificationTime))
fs.delete(f,true);
}
);
But is not working for me, what am I doing wrong? I am having the error in the foreach because type mismacht
