Hortonworks-Certified-Apache-Hadoop-2.0-Developer(Pig and Hive Developer) Sample Questions:

1. Can you use MapReduce to perform a relational join on two large tables sharing a key? Assume that the
two tables are formatted as comma-separated files in HDFS.

A) Yes.
B) No, but it can be done with either Pig or Hive.
C) Yes, but only if one of the tables fits into memory
D) No, MapReduce cannot perform relational operations.
E) Yes, so long as both tables fit into memory.

2. A client application creates an HDFS file named foo.txt with a replication factor of 3. Identify which best
describes the file access rules in HDFS if the file has a single block that is stored on data nodes A, B and
C?

A) Each data node stores a copy of the file in the local file system with the same name as the HDFS file.
B) Each data node locks the local file to prohibit concurrent readers and writers of the file.
C) The file will be marked as corrupted if data node B fails during the creation of the file.
D) The file can be accessed if at least one of the data nodes storing the file is available.

3. When can a reduce class also serve as a combiner without affecting the output of a MapReduce program?
