             Summary: Enable Replica Placement Value Per Rack
                 Key: HDFS-14220
                 URL: https://issues.apache.org/jira/browse/HDFS-14220
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: datanode
    Affects Versions: 2.7.1
            Reporter: Amithsha


By default, Replica placement per rack will be taken care by  
BlockPlacementPolicyDefault.java .

With 2 if conditions 
 # numOfRacks <1 
 # numOfRacks > 1

and the placement will happen as 1 on localrack, 2 on remote rack.

If a user needs max of 1 replica per rack then he need to modify the  
BlockPlacementPolicyDefault.java
