Walter Su commented on HDFS-8073:
---------------------------------
Hi, [~szetszwo]! I think let numOfReplicas=0 is useless. I removed it so the
code looks clean.
Sorry about that. I'll leave it alone. Now 003 patch only moves code.
> Split BlockPlacementPolicyDefault.chooseTarget(..) so it can be easily
> overrided.

> We want to implement a placement policy( eg. HDFS-7891) based on default
> policy. It'll be easier if we could split
> BlockPlacementPolicyDefault.chooseTarget(..).
