Hello everyone

I am using RandomSampleLoader to load 1000 tuples per mapper. I have 11 map 
jobs in a small dataset and 109 map jobs in a large dataset. 

I am expecting 11000 tuples from the small dataset and 109000 tuples from the 
large dataset. But the actual number of tuples that I get is always more than 
what I expected. In small dataset case I am getting 15000 tuples whereas in 
large dataset case I am getting 145000 (sometimes 150000) tuples. 

Is this a bug? or is it an expected behavior? If reservoir sampling is used by 
all mappers then why is the number of total samples is more?

Thanks
