> Key: SPARK-26315
> URL: https://issues.apache.org/jira/browse/SPARK-26315
> Project: Spark
> Issue Type: Improvement
> Components: MLlib, PySpark
> Affects Versions: 2.3.2
> Reporter: Song Ci
> Priority: Major
>
> when I was using
> {code:java}
> // code placeholder
> BucketedRandomProjectionLSHModel.approxSimilarityJoin(dt_features, dt_features, distCol="EuclideanDistance", threshold=20.)
> {code}
> I was confused then that this method reported an exception some java method (dataset, dataset, integer, string) fingerprint can not be found.... I think if I give an integer, and the python method of pyspark should be auto-cast this to float if needed.
