                 Key: HIVE-7643
                 URL: https://issues.apache.org/jira/browse/HIVE-7643
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li


ExecMapper contain static states, static variable "done" for example. Spark executor may execute multi tasks concurrently, ExecMapper static state updated by one task would influence the logic of another task, which may lead to unpredictable result.
