> Scenario:
> =========
> Start NN and three DN"S
> Get the datanode to which blocks has to be replicated.

> {code}
> nodes = nextBlockOutputStream(src);
> {code}
> Before start writing to the DN ,kill the primary DN.
> {code}
> // write out data to remote datanode
> blockStream.write(buf.array(), buf.position(), buf.remaining());
> blockStream.flush();
> {code}
