  Replication factor means how many copies of hdfs block should be copied (replicated) in Hadoop cluster.
  
  Default replication factor is = 3
  Minimum replication factor that can be set = 1
  Maximum replication factor that can be set = 512
  
  One can set the replication factor in hdfs-site xml file as follows:
  
  <property>
  <name>dfs.replication</name>
  <value>512</value>
  </property>
