Canopy Generation

[Mark]

Is there an easy way to know hot many canopies where generated after 
running the canopy generation tool?

I tried viewing the file clusters-0/part-r-00000 via seqdumper but it 
always returns:

Key: C-0: Value: C-0: 
{437:0.005630003188145648,478:0.006034746778989781,591:0.020761514762446885...
Count: 1

Should there be multiple key value pairs or just this one?

Thanks
