title: Split size vs Block size in Hadoop
body: <p>What is relationship between split size and block size in Hadoop? As I read in <a href="http://willddy.github.io/2012/08/25/Hadoop-Split-and-Block.html" rel="noreferrer">this</a>, split size must be n-times of block size (n is an integer and n > 0), is this correct? Is there any must in relationship between split size and block size?</p>
