Subject [jira] [Created] (SPARK-31651) Improve handling for the case of different barrier sync types in a single sync
Date Wed, 06 May 2020 09:35:00 GMT
wuyi created SPARK-31651:
----------------------------

             Summary: Improve handling for the case of different barrier sync types in a single
sync
                 Key: SPARK-31651
                 URL: https://issues.apache.org/jira/browse/SPARK-31651
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: wuyi


Currently, we use cleanupBarrierStage when detecting different barrier sync types in a single
sync. This cause a problem that a new `ContextBarrierState` can be created again if there's
following requesters on the way. And those corresponding tasks will fail because of killing
instead of different barrier sync types deteced.
