Cloudera Certified Developer for Apache Hadoop (CCDH) Sample Questions:
Question 1
For each intermediate key, each reducer task can emit:
A. As many final key-value pairs as desired, but they must have the same type as the intermediate key-value pairs.
B. As many final key-value pairs as desired, as long as all the keys have the same type and all the values have the same type.
C. One final key-value pair per value associated with the key; no restrictions on the type.
D. As many final key-value pairs as desired. There are no restrictions on the types of those key-value pairs (i.e., they can be heterogeneous).
E. One final key-value pair per key; no restrictions on the type.
Question 2
Given a directory of files with the following structure: line number, tab character, string:
Example:
1abialkjfjkaoasdfjksdlkjhqweroij
2kadfjhuwqounahagtnbvaswslmnbfgy
3kjfteiomndscxeqalkzhtopedkfsikj
You want to send each line as one record to your Mapper. Which InputFormat should you use to complete the line: conf.setInputFormat (____.class) ; ?
A. KeyValueFileInputFormat
B. SequenceFileInputFormat
C. SequenceFileAsTextInputFormat
D. BDBInputFormat
Question 3
Assuming default settings, which best describes the order of data provided to a reducer's reduce method:
A. Both the keys and values passed to a reducer always appear in sorted order.
B. The keys given to a reducer are in sorted order but the values associated with each key are in no predictable order
C. Neither keys nor values are in any predictable order.
D. The keys given to a reducer aren't in a predictable order, but the values associated with those keys always are.
Question 4
You use the hadoop fs -put command to write a 300 MB file using and 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 life?
A. They would see the current of the file through the last completed block.
B. They would see no content until the whole file written and closed.
C. They would see Hadoop throw an ConcurrentFileAccessException when they try to access this file.
D. They would see the current state of the file, up to the last bit written by the command.
Question 5
Determine which best describes when the reduce method is 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 only after all intermediate data has been copied and sorted.
B. 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.
C. 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.
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.
