title: How to calculate No of cores,executors, amount of memory in Spark Job
body: <p>Can someone help me in finding the no of cores,executors,memory ..etc in spark.</p>
  
  <p>I am using open source apache spark cluster </p>
  
  <p>below is my configuration - </p>
  
  <pre><code>Total 6 nodes(1 master and 5 slaves). 
  32GB per node
  16 vCPUS per node
  </code></pre>
  
  <p>Note - seems like master node is not participating in computation, that's how cluster setup.</p>
  
  <pre><code>--driver-memory = ?
  
  --executor-memory =? 
  
  --executor-cores =?
  
  --num-executors =?
  </code></pre>
