1) Consider a Hadoop job that will result in 78 blocks of outputto HDFS. Suppose that writing an output block to HDFS takes 1minute. The HDFS replication factor is set to 3 (for simplicity, wecharge reducers for the cost of writing replicated blocks). a) Howlong will it take for the reducer to write the job output on a5-node Hadoop cluster?
b) How long will it take for reducer(s) to write the job outputto 10 Hadoop worker nodes?(Assume that data is distributed evenlyand replication factor is set to 1)
c) How long will it take for reducer(s) to write the job outputto 10
