> Support generic item type in PrefixSpan
> ---------------------------------------
>
> Key: SPARK-9000
> URL: https://issues.apache.org/jira/browse/SPARK-9000
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.5.0
> Reporter: Xiangrui Meng
> Priority: Critical
>
> In SPARK-6487, we only support Int type. It requires users to encode other
> types into integer to use PrefixSpan. We should be able to do this inside
> PrefixSpan, similar to FPGrowth. This should be done before 1.5 since it
> changes APIs.
