> In a cluster where there is replication going on, I've noticed that this is always 0:
> {code}
>     "source.shippedKBs" : 0,
> {code}
> Looking at the source reveals why:
> {code}
>           metrics.shipBatch(currentNbOperations, currentSize / 1024, currentNbHFiles);
> {code}
> It is always undercounting because we discard remaining bytes after KB boundary. This is specially a problem when we are always shipping small batches <1KB.
