It would be better to add one more transformation step before saveAsTextFile,
like:
rdd.map(tuple => "%s,%s,%s".format(tuple._1, tuple._2,
tuple._3)).saveAsTextFile(...)
By manually convert to the format you what, and then write to HDFS.

you can just use something like this:
myRdd(_.productIterator.mkString(",")).saveAsTextFile
