and this is the error showed up:

WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
    at LogFile.TraitServeur.main(TraitServeur.java:63)"

the line error 63 is about the output format:

FileOutputFormat.setOutputPath(conf, new Path(args[1]))

What I have tried:

this is my code source
