> When final merge is disabled (without pipelining), wrong stats was sent out 
> in the last event. 
> It was based on {{numRecordsPerPartition}} which contains the overall 
> partition data. It should be ideally be based on the spill result and its 
> buffers.
> Also, {{finalSpill}} was unncessarily sending events when no data was present 
> (i.e, when currentBuffer didn't have any data).  This can be optimized to 
> reduce the number of events being sent across.
