>                 Key: REEF-1223
>                 URL: https://issues.apache.org/jira/browse/REEF-1223
>             Project: REEF
>          Issue Type: New Feature
>          Components: IMRU
>            Reporter: Julia
>            Assignee: Julia

> Currently in .Net Group Communication and IMRU scenario, if one of the Evaluator failed
for whatever reason, all the Evaluators will be killed by the driver. 
> There are multiple levels of fault tolerant. The scenario we would like to support in
this JIRA is:
> *  When an evaluator failed, this failed evaluator will be killed and other good Evaluators
will stay, but all the tasks running on those Evaluators will be stopped. 
> *  A new Evaluator will be requested and started with the original task. 
> *  Same tasks will be resubmitted to the rest the Evaluators
> *  The topology of those tasks will be kept in the same group communication as before
> *  The data that have been downloaded in those good Evaluators will stay.
