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

             Summary: Degenerate the current ConcurrentHashMap type of intermediateResults to a normal HashMap type.
                 Key: FLINK-14612
                 URL: https://issues.apache.org/jira/browse/FLINK-14612
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: vinoyang


After FLINK-11417, we made ExecutionGraph be a single-thread mode. It will no longer be plagued by concurrency issues. So, we can degenerate the current ConcurrentHashMap type of intermediateResults to a normal HashMap type.
