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

1. Which HDFS command copies an HDFS file named foo to the local filesystem as localFoo?

A) hadoop fs -put foo LocalFoo
B) hadoop fs -get foo LocalFoo
C) hadoop fs -Is foo
D) hadoop -cp foo LocalFoo

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

A) The default partitioner assigns key-values pairs to reduces based on an internal random number generator.
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 implements a round-robin strategy, shuffling the key-value pairs to each reducer in turn. This ensures an event partition of the key space.
D) 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.
E) 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.

3. Which describes how a client reads a file from HDFS?

A) The client contacts the NameNode for the block location(s). The NameNode contacts the DataNode that holds the requested data block. Data is transferred from the DataNode to the NameNode, and then from the NameNode to the client.
B) The client queries all DataNodes in parallel. The DataNode that contains the requested data responds directly to the client. The client reads the data directly off the DataNode.
C) The client queries the NameNode for the block location(s). The NameNode returns the block location(s) to the client. The client reads the data directory off the DataNode(s).
D) The client contacts the NameNode for the block location(s). The NameNode then queries the DataNodes for block locations. The DataNodes respond to the NameNode, and the NameNode redirects the client to the DataNode that holds the requested data block(s). The client then reads the data directly off the DataNode.

4. You are developing a combiner that takes as input Text keys, IntWritable values, and emits Text keys, IntWritable values. Which interface should your class implement?

A) Reducer <Text, IntWritable, Text, IntWritable>
B) Combiner <Text, IntWritable, Text, IntWritable>
C) Combiner <Text, Text, IntWritable, IntWritable>
D) Mapper <Text, IntWritable, Text, IntWritable>
E) Reducer <Text, Text, IntWritable, IntWritable>

5. In a MapReduce job, you want each of your input files processed by a single map task. How do you configure a MapReduce job so that a single map task processes each input file regardless of how many blocks the input file occupies?

A) Write a custom MapRunner that iterates over all key-value pairs in the entire file.
B) Set the number of mappers equal to the number of input files you want to process.
C) Increase the parameter that controls minimum split size in the job configuration.
D) Write a custom FileInputFormat and override the method isSplitable to always return false.
