Robert Joseph Evans commented on MAPREDUCE-4089:
------------------------------------------------
The test failures appear to be caused by either existing issues or Bind errors,
just like before. All of the failures are in the RM, which has no dependency
on the code that was changed with this patch.
> Hung Tasks never time out.

> 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.
