B) jar MyJar.jar
C) hadoop jar MyJar.jar MyDriverClass inputdir outputdir
D) hadoop jar class MyJar.jar MyDriverClass inputdir outputdir

2. When is the reduce method 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) 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.
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) 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.

This is called:

A) Default Partitioner
B) IdentityMapper
C) IdentityReducer
D) Speculative Execution
E) Combiner

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