Hortonworks Apache-Hadoop-Developer Exam Syllabus Topics:

Hortonworks Hadoop 2.0 Certification exam for Pig and Hive Developer Sample Questions:

1. In Hadoop 2.0, which TWO of the following processes work together to provide automatic failover of the NameNode? Choose 2 answers

A) JournalNode
B) ZooKeeper
C) ZKFailoverController
D) QuorumManager

2. What does the following command do?
register '/piggyban):/pig-files.jar';

A) Assigns a name to a user-defined function or streaming command
B) Invokes the user-defined functions contained in the jar file
C) Specifies the location of the JAR file containing the user-defined functions
D) Transforms Pig user-defined functions into a format that Hive can accept

3. You have user profile records in your OLPT database, that you want to join with web logs you have already ingested into the Hadoop file system. How will you obtain these user records?

A) Ingest with Hadoop Streaming
B) Hive LOAD DATA command
C) Ingest with Flume agents
D) Sqoop import
E) HDFS command
F) Pig LOAD command

4. Workflows expressed in Oozie can contain:

A) Sequences of MapReduce and Pig. These sequences can be combined with other actions including forks, decision points, and path joins.
B) Sequences of MapReduce and Pig jobs. These are limited to linear sequences of actions with exception handlers but no forks.
C) Iterntive repetition of MapReduce jobs until a desired answer or state is reached.
D) Sequences of MapReduce job only; on Pig on Hive tasks or jobs. These MapReduce sequences can be combined with forks and path joins.

5. Analyze each scenario below and indentify which best describes the behavior of the default partitioner?

A) 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.
B) 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.
C) 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.
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 assigns key-values pairs to reduces based on an internal random number generator.
