Looks you compiled the codes with one Scala version but ran your app using a different incompatible version.
BTW, you should not use PrintWriter like this to save your results. There may be multiple tasks running at the same host, and your job will fail because you are trying to write to the same file. Could you convert your data to String using "map" and use "saveAsTextFile" or other "save" methods?
