Zhijie Shen commented on YARN-542:
----------------------------------
@Vinod , how about conservatively changing max attempts to 2, if there's no
strong motivation to give AM multiple retry chances?
> Change the default AM retry value to be not one

> Today, the AM max-retries is set to 1 which is a bad choice. AM max-retries
> accounts for both AM level failures as well as container crashes due to
> localization issue, lost nodes etc. To account for AM crashes due to problems
> that are not caused by user code, mainly lost nodes, we want to give AMs some
> retires.
> I propose we change it to atleast two. Can change it to 4 to match other
> retry-configs.
