Problem Scenario 38 : You have been given an RDD as below,

val rdd: RDD[Array[Byte]]

Now you have to save this RDD as a SequenceFile. And below is the code snippet.

import org.apache.hadoop.io.compress.GzipCodec

rdd.map(bytesArray => (A.get(), new B(bytesArray))).saveAsSequenceFile('7output/path",classOt[GzipCodec])

What would be the correct replacement for A and B in above snippet.
