As you can see, the result of histogram() is a pair of arrays, since
of course it's small. It's not necessary and in fact is huge overkill
to make it back into an RDD so you can save it across a bunch of
partitions.
This isn't a job for Spark, but simple Scala code. Off the top of my
head (maybe n
Hi,
histogram method return normal scala types not a RDD. So you will not
have saveAsTextFile.
You can use makeRDD method make a rdd out of the data and saveAsObject file
val hist = a.histogram(10)
val histRDD = sc.makeRDD(hist)
histRDD.saveAsObjectFile(path)
