> Components: MLlib

> Reporter: Littlestar
> Priority: Minor
>
> Spark MLlib fpm#FPGrowth minSupport should use long instead
> ==============
> val minCount = math.ceil(minSupport * count).toLong
> because:
> 1. [count]numbers of datasets is not kown before read.
> 2. [minSupport ]double precision.
> from mahout#FPGrowthDriver.java
> addOption("minSupport", "s", "(Optional) The minimum number of times a
> co-occurrence must be present."
> + " Default Value: 3", "3");
> I just want to set minCount=2 for test.
> Thanks.
