[jira] [Created] (SPARK-8853) FPGrowth is not Java-Friendly

Feynman Liang created SPARK-8853:
------------------------------------

             Summary: FPGrowth is not Java-Friendly
                 Key: SPARK-8853
                 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
```java
ClassTag<String> tag = scala.reflect.ClassTag$.MODULE$.apply(String.class)

FPGrowthModel<String> model = new FPGrowthModel<String>(rdd, 35L, tag);
JavaRDD<AssociationRules.Rule<String>> results = (new AssociationRules()).runJava(model);
```
