> Hardcoded task ping timeout kills tasks localizing large amounts of data

> Key: MAPREDUCE-4817
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4817
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster, mr-am
> Affects Versions: 0.23.3, 2.0.3-alpha
> Reporter: Jason Lowe
> Assignee: Thomas Graves
> Priority: Critical
> Attachments: MAPREDUCE-4817.patch, MAPREDUCE-4817.patch

>
> When a task is launched and spends more than 5 minutes localizing files, the
> AM will kill the task due to ping timeout. The AM's TaskHeartbeatHandler
> currently tracks tasks via a progress timeout and a ping timeout. The
> progress timeout can be controlled via mapreduce.task.timeout and even
> disabled by setting the property to 0. The ping timeout, however, is
> hardcoded to 5 minutes and cannot be configured. Therefore if the task takes
> too long localizing, it never gets running in order to ping back to the AM
> and the AM kills it due to ping timeout.
