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.
the entire 1000-node cluster can complete these MapReduce operations in 100 seconds then doubling the CPU performance (task processing rate) of each machine in the cluster may improve performance somewhat but not significantly.
