[jira] [Updated] (REEF-1380) HeartbeatManager can trigger a NullReferenceException if Evaluator operation state is [OPERATIONAL] and runtime state is [FAILED]

     [ https://issues.apache.org/jira/browse/REEF-1380?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Chung updated REEF-1380:
-------------------------------
    Description: 
This is caused by the following line of code:
{code}
if (_evaluatorSettings.OperationState == EvaluatorOperationState.OPERATIONAL && EvaluatorRuntime.State == State.RUNNING)
{
  // code
} else {
  // code
  DriverInformation driverInformation = _driverConnection.GetDriverInformation();
  // code
}
{code}

We should not call {{_driverConnection.GetDriverInformation();}} on a failed Evaluator.
