title: Is the Hadoop Split size the same?
body: <p><strong>A hadoop input splits are same size</strong>, and I knew it could be customized from the developer.</p>

  <p>In the attached figure, <strong>input split size is not same</strong>. Each input split shape is different. I'm confused about the fact that the input sizes were not the same.</p>
  
  <p>The Hadoop definitive guide also mentioned that the input split size is the same.</p>
  
  <p>Does the system make the input size random by the specified size?</p>
