             Summary: MapWork shouldn't be reused when Spark task fails during 
initialization
                 Key: HIVE-19439
                 URL: https://issues.apache.org/jira/browse/HIVE-19439
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Rui Li


Issue identified in HIVE-19388. When a Spark task fails during initializing the 
map operator, the task is retried with the same MapWork retrieved from cache. 
This can be problematic because the MapWork may be partially initialized, e.g. 
some operators are already in INIT state.
