[jira] [Created] (MAHOUT-1921) DSSVD Propagates cache hint

Trevor Grant created MAHOUT-1921:
------------------------------------

             Summary: DSSVD Propagates cache hint
                 Key: MAHOUT-1921
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1921
             Project: Mahout
          Issue Type: Improvement
          Components: Math
    Affects Versions: 0.13.0
            Reporter: Trevor Grant
            Priority: Minor
             Fix For: 0.13.0


The DSSVD does lots of check pointing, but currently only the default checkpoint cacheHint is given.  

The user should be able to pass a checkpointing hint as this can lead to dramatic performance issues in some cases.
