-----------------------------------------
Summary: ALS performs unnecessary casting on item and user ids
Key: SPARK-19733
URL: https://issues.apache.org/jira/browse/SPARK-19733
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 2.1.0, 2.0.1, 2.0.0, 1.6.3
Reporter: Vasilis Vryniotis
The ALS is performing unnecessary casting to the user and item ids (to double).
I believe this is because the protected checkedCast() method requires a double
input. This can be avoided by refactroing the code of checkedCast method.
