> Hive-Bolt can lose tuples when flushing data

> In HiveBolt's execute method tuples are ack'd as they are received. When a
> batchsize of tuples has been received, the writers are flushed. However, if
> the flush fails only the most recent tuple will be marked as failed. All
> prior tuples will already have been ack'd. This creates a window for data
> loss.
