> We can improve some RPC performance if the extendedBlock is not null.
> Such as addBlock, getAdditionalDatanode and complete.
> Since HDFS encourages user to write large files, so the extendedBlock is not null in
most case.
> In the scenario of Multiple Destination and large file, the effect is more obvious.
