Subject [jira] [Commented] (REEF-1447) Validate Task close failure => FailedEvaluator Event (task has not yet finished)
Date Tue, 21 Jun 2016 22:35:57 GMT

    [ https://issues.apache.org/jira/browse/REEF-1447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15342925#comment-15342925
] 

Julia commented on REEF-1447:
-----------------------------

In fault tolerant, we depend on the following scenario:

1.Driver sends event to close task
2. Task throw IMRUSystemException
3. Evaluaor sends FailedTask to Driver
4. Driver uses FailedTask to record if a task is killed before resubmit

If task close handler throw Evaluator exception, we won't be able to do IMRU fault tolerant
as all.

> We need to validate that an {{Exception}} in {{TaskCloseHandler}} triggers a {{FailedEvaluator}}
event on the Driver, if the Task has not yet completed.
