-----------------------------------
I don't understand, this is the same as SPARK-20180?
> Change default maxPatternLength value to Int.MaxValue in PrefixSpan

> Key: SPARK-20203
> URL: https://issues.apache.org/jira/browse/SPARK-20203
> Project: Spark
> Issue Type: Wish

> Original Estimate: 0h

> I think changing the default value to Int.MaxValue would
> be more user friendly. At least for new user.
> Personally, when I run an algorithm, I expect it to find all solution by
> default. And a limited number of them, when I set the parameters so.
> The current implementation limit the length of solution patterns to 10.
> Thus preventing all solution to be printed when running slightly large
> datasets.
