Akira Ajisaka commented on MAPREDUCE-7198:
------------------------------------------
Thanks [~iwasakims] for the comment.
bq. Should "mapreduce.task.stuck.timeout-ms = 0" mean disabling the timeout
rather than "mapreduce.task.timeout = 0"?
Agreed.
bq. If the goal here is to retain previous behaviour before MAPREDUCE-6190 as
task does not timeout only if mapreduce.task.timeout = 0, the
task-stuck-timeout should be disabled by default (by set the value to 0).
My understanding is that the goal here is to provide some way to disable task
timeout for testing purpose, so I'm thinking we don't need to disable the stuck
timeout by default.
> mapreduce.task.timeout=0 configuration used to disable timeout doesn't work

> mapreduce.task.timeout=0 configuration used to disable timeout doesn't work

> fails with stuck timeout, if the TaskStatus is null.

> checkTaskLimits();
> taskStatus.statusUpdate(taskProgress.get(),

> amFeedback = umbilical.statusUpdate(taskId, taskStatus);
> taskFound = amFeedback.getTaskFound();
> taskStatus.clearStatus();
> }
> else {
> // send ping
> amFeedback = umbilical.statusUpdate(taskId, null);
