> {{ClientProtocol}} methods {{addBlock()}} and {{complete()}} need to include additional
parameter - a block, which has been successfully written to data-nodes. By sending this block
to the name-node the client confirms the generation stamp of the block and its length. The
block on the name-node changes its state to committed and will become complete as long as
one of the finalized replicas reported by data-nodes.
