> The AM will timeout a task through mapreduce.task.timeout only when it does
> not hear from the task within the given timeframe. On 1.0 a task must be
> making progress, either by reading input from HDFS, writing output to HDFS,
> writing to a log, or calling a special method to inform it that it is still
> making progress.
> This is because on 0.23 a status update which happens every 3 seconds is
> counted as progress.
