Reading a text file into RDD[Char] instead of RDD[String]

[Michael Lewis]

Hi,

I’m struggling to think of the best way to read a text file into an RDD[Char] 
rather than [String]

I can do: 

sc.textFile(….)  which gives me the Rdd[String],

Can anyone suggest the most efficient way to create the RDD[Char] ? I’m sure 
I’ve missed something simple…

Regards,
Mike

[Sean Owen]

val s = sc.parallelize(Array(foo, bar, baz))

val c = s.flatMap(_.toIterator)

c.collect()
res8: Array[Char] = Array(f, o, o, b, a, r, b, a, z)
