title: HDFS replication factor
body: <p>When I'm uploading a file to HDFS, if I set the replication factor to 1 then the file splits gonna reside on one single machine or the splits would be distributed to multiple machines across the network ? </p>
  
  <pre><code>hadoop fs -D dfs.replication=1 -copyFromLocal file.txt /user/ablimit
  </code></pre>
