Card 10 / 19: 3. [8 points]: Ben Bitdiddle is using a MapReduce cluster (as described in reading #8) to process some data. He finds that some of his programs are running slowly and needs your help to understand which performance enhancements to try. For each of the following MapReduce configurations and suggested enhancements, circle True if the statement about the enhancement is true, and False otherwise.If the performance of the system is not limited by network throughput or the rate at which map tasks can read from or write to the disk, then doubling the number of nodes in the system will probably improve performance if the number of map and reduce tasks is greater than the number of nodes.
A) True
B) False
