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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
