> Hadoop has a built-in mechanism to fail a job if some tasks failed more than 3 times. This mechanism works fine in most scenarios. However, in some other cases, it is highly desirable for the user to change (increase) that number. My current running job demonstrates such a scenario: The job has run more than 2.5 days. It is close to complete (90+%). Everything indicates that it will finish eventually in a day, except for one potential danger: some of the tasks are in their 3rd try! 
> It will be extremely helpful if I can change the maximun number of tries to 6 instead of 4!
