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: 0.4
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.
