>
> 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.
