Cloudera Certified Developer for Apache Hadoop Sample Questions:

1. All keys used for intermediate output from mappers must do which of the following:

A) Override isSplitable
B) Use a comparator for speedy sorting
C) Be compressed using a splittable compression algorithm.
D) Implement WritableComparable
E) Be a subclass of Filelnput-Format

2. You use the hadoop fs -put command to write a 300 MB file using an HDFS block size of 64 MB. Just after this command has finished writing 200 MB of this file, what would another user see when trying to access this file?

A) They would see the content of the file through the last completed block.
B) They would see no content until the whole file is written and closed.
C) They would see the current state of the file, up to the last bit written by the command.
D) They would see Hadoop throw an concurrentFileAccessException when they try to access this file.

3. When is the reduce method first called in a MapReduce job?

A) Reducers start copying intermediate key value pairs from each Mapper as soon as it has completed. The reduce method is called as soon as the intermediate key-value pairs start to arrive.
B) Reducers start copying intermediate key-value pairs from each Mapper as soon as it has completed. The reduce method is called only after all intermediate data has been copied and sorted.
C) Reducers start copying intermediate key-value pairs from each Mapper as soon as it has completed. The programmer can configure in the job what percentage of the intermediate data should arrive before the reduce method begins.
D) Reduce methods and map methods all start at the beginning of a job, in order to provide optimal performance for map-only or reduce-only jobs.

4. You have a large dataset of key-value pairs, where the keys are strings, and the values are integers. For each unique key, you want to identify the largest integer. In writing a MapReduce program to accomplish this, can you take advantage of a combiner?

A) No, a combiner would not be useful in this case.
B) Yes, as long as all the keys fit into memory on each node.
C) Yes, but the number of unique keys must be known in advance.
D) Yes.
E) Yes, as long as all the integer values that share the same key fit into memory on each node.

5. What types of algorithms are difficult to express MapReduce?

A) Large-scale graph algorithms that require one-step link traversal.
B) Text analysis algorithms on large collections of unstructured text (e.g., Web crawls).
C) Relational operations on large amounts of structured and semi structured data.
D) Algorithms that requite global, shared state.
E) Algorithms that require applying the same mathematical function to large numbers of individual binary records.
