Hi,
histogram() returns an object that is a pair of Arrays. There appears to be
no saveAsTextFile() for this paired object.
Currently I am using the following to save the output to a file:
val hist = a.histogram(10)
val arr1 = sc.parallelize(hist._1).saveAsTextFile("file1")
val arr2 = sc.parallelize(hist._2).saveAsTextFile("file2")
Is there a simpler way to save the histogram() result to a file?
thanks
