> Provide operator to truncate lineage without persisting RDD's

> Checkpointing exists in Spark to truncate a lineage chain. I've heard
> requests from some users to allow truncation of lineage in a way that is
> "cheap" and doesn't serialized and persist the RDD. This is possible if the
> user is willing to forgo fault tolerance for that RDD (for instance, for
> shorter running jobs or ones that use a small number of machines). It's
> pretty easy to allow this so we should look into it for Spark 1.5.
