-Re: which part of Hadoop is responsible of distributing the input file fragments to datanodes?
I guess you means to set your own strategy of block distribution.
If this, just hack the code as following clue:
FSNamesystem.getAdditionalBlock() ---> BlockManager.chooseTarget()
And you need to implement your own BlockPlacementPolicy.
Then if the client request addBlock RPC, the NameNode will assign DataNode
to store the replicas as your rules.
