---------------------------------
Summary: Stabilize AsyncRDDActions and expose its methods in Java
API
Key: SPARK-3902
URL: https://issues.apache.org/jira/browse/SPARK-3902
Project: Spark
Issue Type: New Feature
Components: Java API, Spark Core
Reporter: Josh Rosen
The AsyncRDDActions methods are currently the easiest way to determine Spark
jobs' ids for use in progress-monitoring code (see SPARK-2636).
AsyncRDDActions is currently marked as {{@Experimental}}; for 1.2, I think that
we should stabilize this API and expose it in Java, too.
One concern is whether there's a better async API design that we should prefer
over this one as our stable API; I had some ideas for a more general API in
SPARK-3626 (discussed in much greater detail on GitHub:
https://github.com/apache/spark/pull/2482) but decided against the more general
API due to its confusing cancellation semantics. Given this, I'd be
comfortable stabilizing our current API.
