Assume a MapReduce cluster that consists of 32 nodes, each with 4 map slots and 2 reduce slots. The replication factor is set to 3 (there are three replicas of each block). Given a simple word count job with an input size of 320 GB, answer the following questions. a. Suppose the word count job processes the input data at a constant rate of 4 MB/s. Determine a proper block size for the distributed file system considering the efficiency of map tasks as well as their recovery cost. Justify your choice. Given the configuration of the MapReduce cluster, determine how many map tasks will this job have and how many rounds/waves are needed to finish the map phase on this cluster? b. How many reduce tasks should this job have? Justify your configuration.
