------------------------------------

             Summary: ALS factors should be persist in memory and disk
                 Key: SPARK-2777
                 URL: https://issues.apache.org/jira/browse/SPARK-2777
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 1.0.0
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng


Now the factors are persisted in memory only. If they get kicked off by later 
jobs, we have to start the computation from very beginning. A better solution 
should be changing the storage level to MEMORY_AND_DISK.
