title: Is there any memory loss in HDFS if we use small files?
body: <p>I have taken below Quoting from Hadoop - The Definitive Guide:
  Note, however, that small files do not take up any more disk space than is required to store the raw contents of the file. For example, a 1 MB file stored with a block size of 128 MB uses 1 MB of disk space, not 128 MB,</p>
  
  <p>Here my questions</p>
  
  <p>1) 1 MB file stored with a block size of 128 MB uses 1 MB of disk space, not 128 MB.) How does hdfs use the remaining 127M in this block? </p>
  
  <p>2)Is there any chance to store another file in same block?</p>
