Writing RDDs to HDFS

[Ognen Duzlevski]

Is someRDD.saveAsTextFile("hdfs://ip:port/path/final_filename.txt") 
supposed to work? Meaning, can I save files to the HDFS fs this way?

I tried:
val r = sc.parallelize(List(1,2,3,4,5,6,7,8))
r.saveAsTextFile("hdfs://ip:port/path/file.txt")

and it is just hanging. At the same time on my HDFS it created file.txt 
but as a directory which has subdirectories (the final one is empty).

Thanks!
