> The algorithm outputs more patterns that it is needed. 
> I have tested Mahout's PFP-Growth algorithm with the http://www.borgelt.net/fpgrowth.html
FP-Growth implementation. This implementation has an option to generate closed patterns too.

> When I filtered out the sub patterns from the output of Parallel FP-Growth I arrived
to the same result, as in http://www.borgelt.net/fpgrowth.html
> Succinctly, you are not outputting closed items
> I am attaching the dummy DB along with the output of both algorithms
