> The DFSCLient maintains a list of dead node per input steam. When creating
> this DFSInputStream, it may connect to one of the nodes to check final block
> size. If this call fail, this datanode should be put in the dead nodes list
> to save time. If not it will be retried for the block transfer during the
> read, and we're likely to get a timeout.
