QUESTION: 54

With reference to Hadoop MapReduce in Amazon EMR, which of the following best describes "a user-defined unit of processing, mapping roughly to one algorithm that manipulates the data"?

A cluster map
A multi-cluster
A cluster store
A cluster step

Answer(s): D

Explanation:

A cluster step is a user-defined unit of processing, mapping roughly to one algorithm that manipulates the data.
A step is a Hadoop MapReduce application implemented as a Java jar or a streaming program written in Java, Ruby, Perl, Python, PHP, R, or C++.
For example, to count the frequency with which words appear in a document, and output them sorted by the count, the first step would be a MapReduce application which counts the occurrences of each word, and the second step would be a MapReduce application which sorts the output from the first step based on the counts.
