Hortonworks Data Platform Certified Developer Sample Questions:
You want to count the number of occurrences for each unique word in the supplied input data. You've decided to implement this by having your mapper tokenize each word and emit a literal value 1, and then have your reducer increment a counter for each literal 1 it receives. After successful implementing this, it occurs to you that you could optimize this by specifying a combiner. Will you be able to reuse your existing Reduces as your combiner in this case and why or why not?
- A. No, because the sum operation in the reducer is incompatible with the operation of a Combiner.
- B. No, because the Combiner is incompatible with a mapper which doesn't use the same data type for both the key and value.
- C. Yes, because the sum operation is both associative and commutative and the input and output types to the reduce method match.
- D. Yes, because Java is a polymorphic object-oriented language and thus reducer code can be reused as a combiner.
- E. No, because the Reducer and Combiner are separate interfaces.
