-----------------------------------------
Summary: ALSModel recommendAll analogs
Key: SPARK-19535
URL: https://issues.apache.org/jira/browse/SPARK-19535
Project: Spark
Issue Type: New Feature
Components: ML
Affects Versions: 2.2.0
Reporter: Joseph K. Bradley
Assignee: Sue Ann Hong
Add methods analogous to the spark.mllib MatrixFactorizationModel methods
recommendProductsForUsers/UsersForProducts.
The initial implementation should be very simple, using DataFrame joins.
Future work can add optimizations.
I recommend naming them:
* recommendForAllUsers
* recommendForAllItems
