Re: how to use the method saveAsTextFile of a RDD like javaRDD

[Gefei Li]

It is interesting to save a RDD on a disk or HDFS or somethings else as a
set of objects, but I think it's more useful to save it as a text file for
debugging or just as an output file. If we want to reuse a RDD, text file
also works, but perhaps a set of object files will bring a decrease on
executive time. I wonder how much time it can decrease compared with
transforming a text file to a RDD you want, need time to try :)
