Andrew Ray commented on SPARK-8853:
-----------------------------------
But there is no reason to directly create a {{FPGrowthModel}}, proper usage is
something like:
{code}
FPGrowthModel<String> model = new FPGrowth()
.setMinSupport(0.5)
.setNumPartitions(2)
.run(rdd);
{code}
> FPGrowth is not Java-Friendly

> URL: https://issues.apache.org/jira/browse/SPARK-8853
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Reporter: Feynman Liang
>
> {{FPGrowth[Item : ClassTag]}} has a public constructor but uses a
> parameterized type with a context bound {{ClassTag}}, making it difficult to
> instantiate in Java.
> For example, to instantiate one needs to do
> {code:title=Foobar.java|borderStyle=solid}
> import scala.reflect.ClassTag;
> ClassTag<String> tag = scala.reflect.ClassTag$.MODULE$.apply(String.class)
> FPGrowthModel<String> model = new FPGrowthModel<String>(rdd, 35L, tag);
> {code}
