Cloudera Certified Developer for Apache Hadoop (CCDH) Sample Questions:
You need to create a job that does frequency analysis on input data. You will do this by writing a Mapper that uses TextInputFormat and splits each value (a line of text from an input file) into individual characters. For each one of these characters, you will emit the character as a key and an InputWritable as the value. As this will produce proportionally more intermediate data than input data, which two resources should you expect to be bottlenecks?
- A. Processor and network I/O
- B. Processor and RAM
- C. Disk I/O and network I/O
- D. Processor and disk I/O
Correct Answer: C 🗳️
You have the following key-value pairs as output from your Map task:
(the, 1)
(fox, 1)
(faster, 1)
(than, 1)
(the, 1)
(dog, 1)
How many keys will be passed to the Reducer's reduce method?
- A. One
- B. Five
- C. Four
- D. Three
- E. Two
- F. Six
Correct Answer: B 🗳️

Analyze each scenario below and indentify which best describes the behavior of the default partitioner?
- A. The default partitioner computes the hash of the key. Hash values between specific ranges are associated with different buckets, and each bucket is assigned to a specific reducer.
- B. The default partitioner assigns key-values pairs to reduces based on an internal random number generator.
- C. The default partitioner computes the hash of the value and takes the mod of that value with the number of reducers. The result determines the reducer assigned to process the key-value pair.
- D. The default partitioner implements a round-robin strategy, shuffling the key-value pairs to each reducer in turn. This ensures an event partition of the key space.
- E. The default partitioner computes the hash of the key and divides that valule modulo the number of reducers. The result determines the reducer assigned to process the key-value pair.
Correct Answer: E 🗳️
Explanation: Only visible for ActualVCE members. You can sign-up / login (it's free).
You want to understand more about how users browse your public website, such as which pages they visit prior to placing an order. You have a farm of 200 web servers hosting your website. How will you gather this data for your analysis?
- A. Import all users' clicks from your OLTP databases into Hadoop, using Sqoop.
- B. Write a MapReduce job, with the web servers for mappers, and the Hadoop cluster nodes for reduces.
- C. Ingest the server web logs into HDFS using Flume.
- D. Sample the weblogs from the web servers, copying them into Hadoop using curl.
- E. Channel these clickstreams inot Hadoop using Hadoop Streaming.
Correct Answer: C 🗳️
You need to move a file titled "weblogs" into HDFS. When you try to copy the file, you can't. You know you have ample space on your DataNodes. Which action should you take to relieve this situation and store more files in HDFS?
- A. Increase the amount of memory for the NameNode.
- B. Increase the number of disks (or size) for the NameNode.
- C. Increase the block size on all current files in HDFS.
- D. Increase the block size on your remaining files.
- E. Decrease the block size on your remaining files.
- F. Decrease the block size on all current files in HDFS.
