Where does a MapReduce job store the intermediate data output from Mappers?
- A. Stores on the underlying filesystem of the local disk of the machine on which the Reducer.
- B. In HDFS, in temporary directory defined mapred.tmp.dir.
- C. In HDFS, in the job's output directory.
- D. On the underlying filesystem of the local disk of the machine on which the Mapper ran.

You have a cluster running with the FIFO scheduler enabled. You submit a large job A to the
cluster which you expect to run for one hour. Then, you submit job B to the cluster, which you expect to run a couple of minutes only. Let's assume both jobs are running at the same priority.
How does the FIFO scheduler execute the jobs? (Choose 3)
- A. Since job B needs only a few tasks, if might finish before job A completes.
- B. When a job is submitted, all tasks belonging to that job are scheduled.
- C. The order of execution of tasks within a job may vary.
- D. Given jobs A and B submitted in that order, all tasks from job A will be scheduled before all tasks from job B.

Your cluster is running Map v1 (MRv1), with default replication set to 3, and a cluster blocks 64MB. Identify which best describes the file read process when a Client application connects into the cluster and requests a 50MB file?
- A. The client queries the NameNode for the locations of the block, and reads from a random location in the list it receives to eliminate network I/O loads by balancing which nodes it retrieves data from at any given time.
- B. The client queries the NameNode and then retrieves the block from the nearest DataNode to the client and then passes that block back to the client.
- C. The client queries the NameNode for the locations of the block, and reads all three copies. The first copy to complete transfer to the client is the one the client reads as part of Hadoop's execution framework.
- D. The client queries the NameNode for the locations of the block, and reads from the first location in the list of receives.
In HDFS, you view a file with rw-r--r-- set as its permissions. What does this tell you about the file?
- A. As a Filesystem in Userspace (FUSE), HDFS files are available to all user's on a cluster regardless of their underlying POSIX permissions.
- B. The file cannot be run as a MapReduce job
- C. The file cannot be deleted by anyone but the owner
- D. The file cannot be deleted by anyone
- E. The file's contents can be modified by the owner, but no-one else
