             Summary: Not all Completed Evaluator events are received
                 Key: REEF-1980
                 URL: https://issues.apache.org/jira/browse/REEF-1980
             Project: REEF
          Issue Type: Bug
            Reporter: Julia


When there are many evaluators running in cluster like 300, sometimes, one or two CompletedEvaluator
events cannot be received, causing the driver cannot shut down. 

The issues that driver cannot shut down properly seems was introduced in spring of 2017. But
the root cause is not identified yet.
