title: Is there benefit of having faster master node in hadoop cluster?
body: <p>I have recently built a multi-node Hadoop 2.5.0 cluster using few ARM development boards, and I can not decide if I should use same type of board as master, if I should use faster arm board as master, or even if I should use a desktop to be master to manage slave nodes?</p>
  
  <p>Is there any benefit of having master node faster than the slave nodes in the same cluster?</p>
  
  <p>Besides benefits of increased RAM, does increased CPU performance of master node matters?</p>
