MapReduce Cloud Computing Question:
Tell me what is an input reader in reference to mapreduce?
Answer:
The input reader as the name suggests primarily has two functions:
1. Reading the Input
2. Splitting it into sub-parts
The input reader accepts a user entered problem and then it divides/splits the problem into parts which then each are assigned a map function. Also an input reader will always read data from a stable storage source only to avoid problems.
