Hi [~JohnDA] can you please specify what's the row count you expected with the
model above? is it the total number of 5 + 2 + 2 + 4?

> Add Row count property to FPGrowth model

> Key: SPARK-15930
> URL: https://issues.apache.org/jira/browse/SPARK-15930
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.6.1
> Reporter: John Aherne
> Priority: Minor
> Labels: fp-growth, mllib
>
> Add a row count property to MLlib's FPGrowth model.
> When using the model from FPGrowth, a count of the total number of records is
> often necessary.
> It appears that the function already calculates that value when training the
> model, so it would save time not having to do it again outside the model.
> Sorry if this is the wrong place for this kind of stuff. I am new to Jira,
> Spark, and making suggestions.
