Description

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.
