> Key: SPARK-20180
> URL: https://issues.apache.org/jira/browse/SPARK-20180
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 2.1.0
> Reporter: Cyril de Vogelaere
> Priority: Minor
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> Right now, we need to use .setMaxPatternLength() method to
> specify is the maximum pattern length of a sequence. Any pattern longer than
> that won't be outputted.
> The current default maxPatternlength value being 10.
> This should be changed so that with input 0, all pattern of any length would
> be outputted. Additionally, the default value should be changed to 0, so that
> a new user could find all patterns in his dataset without looking at this
> parameter.
