Saikat Kanjilal commented on MAHOUT-319:
----------------------------------------
I would like to help out on this task by building a notion of persisting of
the state generically to fix this and build implementations of an RDBMS, local
disk or HDFS underneath. Let me know if thats ok with you guys. Out of
curiosity when is 0.5 planned to be released?
> SVD solvers should be gracefully stoppable/restartable

> Key: MAHOUT-319
> URL: https://issues.apache.org/jira/browse/MAHOUT-319
> Project: Mahout
> Issue Type: Improvement
> Affects Versions: 0.3
> Reporter: Jake Mannix
> Assignee: Jake Mannix
> Fix For: 0.5
>
>
> LanczosSolver, DistributedLanczosSolver, and HebbianSolver all keep copious
> amounts of memory-resident data which is lost if the app crashes or is killed
> (OOM, forgetting to run in a screen session, and losing net connectivity to
> the server running it, etc...).
> These algorithms (and many other Mahout processes!) should enable a pluggable
> "persist state" mechanism (to HDFS, RDBMS, local disk, key-value store, etc),
> and similarly, a way to pick up and start from such a state.
