> For non-EC files, we have:
> {code}
> protected ExtendedBlock block; // its length is number of bytes acked
> {code}
> For EC files, the size of {{DFSStripedOutputStream#currentBlockGroup}} is incremented
in {{writeChunk}} without waiting for ack. And both {{updatePipeline}} and {{commitBlock}}
are based on size of {{currentBlockGroup}}.
