Joseph K. Bradley commented on SPARK-5561:
------------------------------------------
I'm generalizing this to use for GBTs. But I will keep it in MLlib.
> Generalize PeriodicGraphCheckpointer for RDDs
> ---------------------------------------------
>
> Key: SPARK-5561
> URL: https://issues.apache.org/jira/browse/SPARK-5561
> Project: Spark
> Issue Type: Improvement
> Components: GraphX, MLlib, Spark Core
> Affects Versions: 1.3.0
> Reporter: Joseph K. Bradley
> Assignee: Joseph K. Bradley
>
> PeriodicGraphCheckpointer was introduced for Latent Dirichlet Allocation
> (LDA), but it could be generalized to work with both Graphs and RDDs. It
> should be generalized and moved out of MLlib.
> (For those who are not familiar with it, it tries to automatically handle
> persisting/unpersisting and checkpointing/removing checkpoint files in a
> lineage of Graphs.)
> A generalized version might be immediately useful for:
> * RandomForest
> * Streaming
> * GLMs
