> We should change chooseTarget(..., DatanodeDescriptor writer, ...) to chooseTarget (...,
node writer, ...) as the only important property of writer is to identify other nodes' location
relationship so more generic one could be better. It also helps to cover cases that client
node is not a Datanode also.
