8 b) Write down the adjacency matrix and transition matrix(columns as source and rows as destination) of the following directed graph and compute page rank using Map Reduce for 1 iteration assuming that initial page ranks of each node is 4. Please use the format shown below to show the working of the Map reduce program. Assume that the transition matrix is stored on HDFS in two blocks - columns 1 and 2 are stored on Node 1 and columns 3 and 4 on Node 2 Node 1 Map Node 1Map Intermediate Node Intermediate value key Reduce input key Reduce input value 2 Intermediate key Map Node 2 Map intermediate values Reduce output key Reduce output values
