title: A file bigger than Hadoop cluster storage
body: <ol>
  <li><p>What would happen if a file I store in HDFS is 5GB but there are only 3 DataNodes 1GB each?</p></li>
  <li><p>Lets say I store a file 3GB in HDFS having 4 DataNodes 1GB each. After processing I have some results.txt. What will happen to processed file blocks which are stored in DataNodes? Because if I want to store another 3GB file to process then there won't be enough space for it? Or maybe those blocks get deleted after processing? Should I deleted it myself?</p></li>
