-------------------------------------

             Summary: Make RDDBarrier configurable
                 Key: SPARK-25247
                 URL: https://issues.apache.org/jira/browse/SPARK-25247
             Project: Spark
          Issue Type: Story
          Components: Spark Core
    Affects Versions: 2.4.0
            Reporter: Xiangrui Meng


Currently we only offer one method under `RDDBarrier`. Users might want to have 
better control over a barrier stage, e.g., timeout behavior, failure recovery, 
etc. This Jira is to discuss what options we should provide under RDDBarrier.

 

Note: Users can use multiple RDDBarrier in a single barrier stage. So we also 
need to discuss how to merge the options.
