>             Project: REEF
>          Issue Type: Improvement

> In REEF-1464 we found out that IMRU task cancellation doesn't work properly if the task
is in TCP connection establishment phase. 
> Instead of task stopping fast, it goes through all the connection retries even though
the task it's trying to connect to
> might be already closed. This might take considerable time, depending on settings of
{{MaxConnectionRetry}} and {{SleepTime}}.
> We need to fix this so that task will get cancelled faster even if task is in TCP connection
establishment phase.
> To do this, we need to investigate retry policies which can be used in {{RemoteConnectionRetryHandler}}.
