Subject [jira] [Commented] (REEF-1431) Validate Task Message Receive failure => FailedEvaluator Event
Date Mon, 27 Jun 2016 17:58:52 GMT

    [ https://issues.apache.org/jira/browse/REEF-1431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15351490#comment-15351490
] 

Andrew Chung commented on REEF-1431:
------------------------------------

I've modified this JIRA item to generate a {{FailedEvaluator}} event due to the fact that
receiving a Task message is not tied to the lifecycle of a Task. In other words, if an Exception
is thrown in the {{TaskMessageHandler}}, we are not able to terminate the Task thread to properly
generate a {{FailedTask}} event with all the guarantees that a {{FailedTask}} event should
have, namely the guarantee that the Task has already ended and ability to submit a subsequent
Task on the Evaluator with the {{FailedTask}}.

> We need to validate that an {{Exception}} in the {{TaskMessageHandler}} (receive side)
triggers a {{FailedTask}} event on the Driver.
