bq. For the common case, when the replication factor is three, HDFS's placement 
policy is to put one replica on one node in the local rack, another on a node 
in a different (remote) rack, and the last on a different node in the same 
*remote* rack.

Should actually be: "and the last on a different node in the same *local* rack."
