> Project: HBase
> Issue Type: Sub-task
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Fix For: 2.0.0, 1.3.0, 1.4.0, 0.98.20

>
> 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.
