Robert Joseph Evans reassigned MAPREDUCE-5060:

    Assignee: Robert Joseph Evans
> Fetch failures that time out only count against the first map task
> ------------------------------------------------------------------
>                 Key: MAPREDUCE-5060
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5060
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>            Reporter: Robert Joseph Evans
>            Assignee: Robert Joseph Evans
>            Priority: Critical
> When a fetch failure happens, if the socket has already "connected" it is only counted
against the first map task.  But most of the time it is because of an issue with the Node
itself, not the individual map task, and as such all failures when trying to initiate the
connection should count against all of the tasks.
> This caused a particularly unfortunate job to take an hour an a half longer then it needed
