title: How to Calculate Throughput from TestDFSIO benchmark on hadoop cluster
body: <p>I have a cluster with 11 nodes, 9 being slaves and 2 masters, the same as in <a href="http://more%20details%20of%20the%20OP&#39;s%20setup%20in%20their%20previous%20question:%20https://stackoverflow.com/questions/39223295/how-to-calculate-throughput-from-testdfsio-benchmark-on-hadoop-cluster" rel="nofollow noreferrer">my previous question</a>. I am executing the TestDFSIO benchmark on this cluster, which uses CDH 5.8.0.</p>
  
  <p>I get the below output from the TestDFSIO result. Is this the throughput? or do I need to calculate the throughput from this, like number of files multiplied by the TestDFSIO result througput or something else?</p>
  
  <p>Please let me know how to get the throughput of the whole cluster.</p>
