Trevor Grant created MAHOUT-1922:
------------------------------------

Summary: DSPCA Propagates cache hint
Key: MAHOUT-1922
URL: https://issues.apache.org/jira/browse/MAHOUT-1922
Project: Mahout
Issue Type: Improvement
Components: Math
Affects Versions: 0.13.0
Reporter: Trevor Grant
Priority: Minor

The DSPCA 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.
