Target Version/s:
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.
